Bug also reported upstream: https://bugs.kde.org/show_bug.cgi?id=373180 I think this is the same thing that I've been experiencing for the last week or so (before upgrading to Plasma 5.8.4). Also with Nouveau driver. In my case, it didn't happen when resizing the panel, but doing so caused the freeze as well. In my case, I was able to trigger it by switching desktops, or by creating a large file transfer, which results in a long enough job with a progress indicator in the "i" on the panel. Easier to reproduce with compositing enabled. For about as long as this has been happening, I've had the same issue with mpv while using the openGL video output. The player hangs after some time of playing, especially if I switch desktops or minimize/restore the player window. The sound goes on, so the player itself is fine, just its openGL "surface" is dead. Plasma's issue is probably also related to openGL. CC:

jan-bugs Additional note: VLC with "OpenGL GLX video output (XCB)" also freezes easily. This is with Cauldron fully updated to right now. For the last few days I have been seeing plasma lock-ups where nothing responds to mouse events. Has happened with various different applications running - I can't pin it down to any particular way to reproduce. Switching to tty2 and back to tty1 clears it. I have seen the same after log-in where the panel never appears unless the switch to a different tty (and back) is made. CC:

marja11 After triggering this bug, I tried switching to another virtual console and then back, as mentioned in bug 19869, and it does unfreeze plasmashell. I've switched to using the nvidia proprietary driver for the last few days and there were no freezes. This issue may be caused by the nouveau driver or an interaction between the nouveau driver and the plasmashell or kwin. Testing with another desktop shell and windows manager may clarify this issue. (In reply to PC LX from comment #9) > This issue may be caused by the nouveau driver or > an interaction between the nouveau driver and the plasmashell or kwin. Some things for the record: - I've reproduced this issue with an AMD card using the free Radeon driver. - Other OpenGL-using programs, such as MPV or VLC also suffer from this kind of hang, that's also "restored" the same way: switch to another tty and back. - Comments on this bug https://bugs.mageia.org/show_bug.cgi?id=19869 point to a DRI2 issue, and a possible fix by using DRI3. That's worked so far for me with nouveau. |
