Description quanticcpu2100 2025-02-24 00:17:53 UTC

After logging into Facebook using Firefox 135.0.1 (64-bit) installed via flatpack, KDE Plasma crashes completely while sending a video to a group I'm subscribed to. I have to turn off the computer directly using the power button. The Plasma desktop remains on the screen, but all keyboard and mouse functions stop working. I tried using CRTL+F1, F2,... and it's not possible to access the terminal to reboot. This issue happens several times.

If input breaks, it's not in Plasma, it's in KWin. Moving there.

Please do let us know if you can make it happen again.

The whole graphical interface crashes trying drag and drop a image from dolphin to imgur.com on fireforx 136.0 (64-bit) flatpak.
The entire KDE Plasma freezes and it is necessary to turn off the computer using the power button.

Looks like it was fixed in kernel 6.13.6
