This week in KDE: fewer korners, more multi-cursor, better apps

Rejoice all, for the infamous “Korners” bug has been fixed! This issue caused 3rd-party window decoration themes with rounded corners to display a square blur area when using burred backgrounds. Themes are now able to (and must) specify a mask graphic that will clip the blur area to the visible area of the window decorations. Thanks to Michail Vourlakos for implementing this fix in Plasma 5.25!

But that’s not all in the Big Deal department, for Kate and other KTextEditor-based apps finally have multi-cursor support! You can create multiple cursors in three ways:

  • Alt+Click in different places to add new cursors there
  • Press Alt+Ctrl+up/down to add new cursors on lines above or below the current one
  • Select multiple lines of text and press Alt+Shift+I to put a cursor on each one

Thanks so much to Waqar Ahmed for this amazing work, which will be in Frameworks 5.93!

Web presence

We finally added the Steam Deck to! 🙂 (Momo Cao, right now)

The download link at is now much more prominent (Guillherme Silva, right now)

…And everything else

This blog only covers the tip of the iceberg! Tons of KDE apps whose development I don’t have time to follow aren’t represented here, and I also don’t mention backend refactoring, improved test coverage, and other changes that are generally not user-facing. If you’re hungry for more, check out, where you can find more news from other KDE contributors.

How You Can Help

If you’re a developer, check out our 15-Minute Bug Initiative. Working on these issues makes a big difference quickly! This is the second week with no 15-minute bugs resolved, and it would be nice to refocus on those. I know everyone’s busy, but they ain’t gonna fix themselves. 🙂

Otherwise, have a look at to discover ways to be part of a project that really matters. Each contributor makes a huge difference in KDE; you are not a number or a cog in a machine! You don’t have to already be a programmer, either. I wasn’t when I got started. Try it, you’ll like it! We don’t bite!

Finally, consider making a tax-deductible donation to the KDE e.V. foundation.

  1. Wonderful to see that the infamous “Korners” bug has been fixed! 🎉🎉🎉 Seeing that it was reported in 2018, it must’ve been non-trivial to fix. And now there’s that feeling again of wanting the next Plasma release… 😀

    It’s so good to see continual improvements to Okular, Kate, and Gwenview; they are central, workhorse productivity apps.

  2. KDE became amazing!
    I rarely boot into windows ( just when i need a windows only program, like plc programmer etc).

    But there are still bugs that needs to be addressed in order to be used by everyone.
    For example, my wife boots into windows because of a annoying bug in dolphin that doesn’t pass rhe right kio link when clicking a file from a Samba share. Double clicking a video from a Samba share makes it open with the smb://url, while starting it from terminal ( for example mplayer file) pass rhe correct kio parameters.

    Also, the battery icon with the percentage shown inside doesn’t change when you plug the laptop in.

    Renaming a . txt file still selects the extension and deletes it when you type a new name.

    It’s impossible to drag a Appimage file into the taskbar or create a shortcut without some work.

    Let’s say I have a virtualbox image on the Windows partition. I cannot automount the partition at startup from right click on it or settings. Everyone I start virtualbox i need to click the partition to mount it first.

    Format USB drive with right click menu its a must for beginners like my wife.. kparted or gparted? They won’t remember that

    A dodgy usb cable. It makes no sound when you connect it/disconnect it. How would i know if a USB is plugged in or not? dmesg or lsusb all the time? We needs sounds on connect/disconnect usb devices🤔

    Another one is running software as root. The open/save as dialogue would take you into the root home by default.. this will trow newcomers off..

    These are just some of the things that needs to be addressed in order to attract newcomers.


    1. Did you open tickets for theses? Some of these sound like interesting discussion points (I can offer some workarounds, especially for things that I don’t think should be features – like automatically mounting Windows partitions) or could be easily fixed (such as the remaining behaviour), but no one can fix problems they don’t know about…

    2. I agree on some nitpicks like format a pendrive. Yesterday I needed to format a pendrive with W10 iso from Manjaro but I couldn’t, apps like IsoImageWriter or Gparted didn’t work, however it did from an already installed W10 VM (VirtualBox) and the Rufus app.

      I add other desires such as:

      – Dolphin in full screen mode
      – Dolphin has a shortcut to create a file
      – Dolphin save the tabs state after a crash or unexpected shutdown
      – Dolphin – making the “Find” toolbar botton a toggle-able button
      – Files on the desktop don’t change position after restart


  3. > In Gwenview, shortcuts for “go to next” and “go to previous” no longer stop working once you reach a video file Thank you, Elliot Lester! That was such an annoying bug. I every time needed to close gwenview when reach the videofile when viewing video+photo contents.

  4. Okular is just an awesome program. I use it (obviously) at home on my general purpose computer, and at work on my laptop via Windows App Store. Love it, and to see this new welcome screen with recently view document is great.

    1. Interesting, I for one dislike round buttons way more than the corners bug so I kinda used to live with it. But anyway I hope the dev of ClassiK theme will adapt it to the changes.


  5. Only want to mention that I have been using Skanpage and it is great!

    Apps like Skanpage are becoming increasingly more important since the big brands (e.g. HP) now forces the users to create online accounts in order to scan, which is a serious privacy concern since paper documents these days are primarily used for very privacy sensitive information (e.g. financial, law and health related).

    I think it would be great if Skanpage made it to the Windows store.

    One thing I would like though is the ability to change contrast/brightness for some few cases where the documents has some very faint signatures/stamps.

    Other than that, thank you all! Outstanding work!


  6. What a great set of goodies! Huge thanks to Jan Blackquill for her(?) wonderful work on so many areas of KDE that coincidentally often are my major gripes with KDE.
    Other are doing amazing work too, thank you all guys.

    Btw Neon just got another convert from Windows as I managed to convict my elder brother to install it. Albeit some hiccups everything is good so far.


  7. Nice!

    One small bug I found in settings, when you toggle a switch via Alt+Key, they “Apply” Button doesn’t get enabled. If you click the same toggle with the mouse it does.

    Please forgive me, but I don’t want to make an account just to report this bug I hope you can relay it


  8. I just discover now thanks to this post that 4 fingers touchpad-swiping is a thing, is that configurable somewhere? Could it be made more “discoverable”?


    1. I’d like to know too – this is something I miss dearly. Up to now I thought KDE simply couldn’t do that and you need other software (like Fusuma) for that. Or is this a Wayland-only thing (I’m a Nvidia hostage)? Would be really great if we finally catch up with all other players (Gnome, Win, Mac…).


    2. Yes, touchpad gestures are a Wayland-only thing (as they are on GNOME too). We’re working on actively improving them, so there’ll be some good stuff in Plasma 5.25!


  9. if you say “Current number of bugs: 81, same as last week.” Does it mean, x bugs got fixed and x new appeared, or that nothing moved? Would be nice if you could mention in case of x>0!


    1. When people fix any of them, I list them here. So this week it means “no new bugs, but also nobody fixed any of them.”


  10. I randomly installed Endeavour in a VM yesterday and was surprised to see the corners bug was 100% fixed. I wasn’t sure when it happened, but good timing I guess.


  11. Thank you for the multicursor support, that was one of two features I missed in Kate, the other being virtual whitespace. Could ye please add it (ye could possibly utilize some code from the block selection mode)? I would like to help, but C++ is not my field of expertise. Were ye to add it, I could leave Komodo IDE (I enabled the virtual whitespace via Scintilla scripting, but it’s very buggy).


  12. Hello!

    Does anybody know what happened to the header separation in notificacions?
    Is it gone/reverted in Frameworks 5.92 or is it something on my end?
