System details:
- Operating System: Arch Linux
- KDE Plasma Version: 5.25.90
- KDE Frameworks Version: 5.98.0
- Qt Version: 5.15.6
- Graphics Platform: X11
I have been trying to debug this, but have absolutely no idea what they have changed for the 5.26 beta that is causing this. I am finding the 5.26 beta unstable in general (crashing in general, even if an opaque override isn't set), and notice the backtraces don't even mention Klassy.
Debug help here would be greatly appreciated.
I'm having a crash but on Wayland. The whole screen locks up (for only one display in multi monitor set ups, curiously) and all I can do to solve it is kill kwin process entirely or reboot. Upon checking journalctl, this appeared for me:
Oct 10 14:13:27 lenovoSUSE kwin_wayland[2312]:kwin_wayland_drm: an error occurred while swapping buffers "EGL_BAD_SURFACE"
I'm trying to figure out if there is something on driver side that may be causing it but the trigger comes from Klassy. If I have transparency activated, any window that, at some point, makes it opaque, it makes the session lock up. I did some tests here and it appears the same symptoms of the issue above happen. If I set to opaque in the Window Specific Overrides for any window, when these applications are launched, the error above occurs. However, I noticed the exact same behavior happening when I try launching Inkscape, which didn't have an override.
I'm on openSUSE Tumbleweed with Liquorix Kernel 5.19.14-lqx1-3-liquorix.

I have the same problem since plasma-5.26. I thought it was plasma and filed a bug report.

It is also Plasma as there were no problems in 5.25. I can't believe they have released a final 5.26 with whatever this change is! :(
Do you have a link to your bug report?
I think you are right for changes in 5.26. My crashs seems to happen with some gtk applications especially firefox. I changed klassy for breeze , screens problems seems to be solved but other issues remains.
I think I'm having the same freezing issue. I didn't see this bug report, so I created one at bugs.kde.org.
Here's a link to that report, if you're interested, @paulmcauley https://bugs.kde.org/show_bug.cgi?id=460486

Could you reopen your bug report? Something has changed in Plasma 5.26 and need to narrow down what it is.
Same issue here using Klassy on wayland.
Seems to happen mostly with Firefox or Thunderbird. It is not 100% reproducible, sometimes it happens right after boot when first launching, sometimes after some time when i try to open a new window.
I am also getting the kwin_wayland_drm: an error occurred while swapping buffers "EGL_BAD_SURFACE"
error like in the 459814 report.
P.S.: This issue might be related to 459778 – Screen occasionally freezes when launching application
Same issue here using Klassy on KDE Wayland. Using the default 'Breeze' decorations doesn't seem to cause the issue.
Randomly happens when opening Sublime Text/Merge and sometimes even just KWrite and Kate, but not necessarily all the time. I can do the Ctrl+Alt+F1-F12 shortcut to reboot it safely but the TTY where Plasma shell is running is completely frozen. Keyboard and mouse inputs still work fine and wakes up the screen when it's about to go to standby.
Also getting kwin_wayland_drm: an error occurred while swapping buffers "EGL_BAD_SURFACE" on journalctl when it happens.
I'm on Fedora 36 with zawertun's KDE Plasma COPR running kernel 5.19.16. Also happens on openSUSE Tumbleweed with Plasma 5.26.0 and kernel 6.0.1 when I tested it. If it helps, I'm running on Intel UHD Graphics.
If it also helps, KWin recently got a feature where applications running in "legacy mode" (or, XWayland) can scale by themselves. The feature is on by default. Haven't tested if this is what causes the issue though as it randomly happens for me.

Seems to be a plasma bug. A patch is tested.

After updating to plasma 5.26.2 the crash only happens if window shadows are enabled
