Comment 2 Nicolas Fella 2023-10-02 19:30:33 UTC

Created attachment 162032 [details]
Backtrace of kwin_wayland during the freeze

Comment 3 Nate Graham 2023-10-07 02:36:59 UTC

Can reproduce even when no external screens are involved.

Comment 4 Nate Graham 2023-10-10 13:44:24 UTC

This is causing me to lose work; bumping to critical.

Comment 5 Nicolas Fella 2023-10-10 13:49:05 UTC

My bug does *not* happen unless there's an external screen and the internal one is disabled, so chances are you have a different root cause. Please file a separate bug

Comment 6 Zamundaaa 2023-10-27 14:03:05 UTC

Can't reproduce with current git master; closing and opening the lid causes a very small pause (one or two frames) each time, but that's all it does.

Closing and opening the lid without an external monitor connected also works correctly for me (at least as far as KWin's concerned; plasmashell reliably crashes)

Comment 7 Nate Graham 2023-10-27 14:04:30 UTC

It may be related to the plasmashell crash, and how drkonqi handles it. Kai has been investigating that and found that if he deletes the `drkonqi` binary it stops happening.

Comment 8 Zamundaaa 2023-11-09 11:42:52 UTC

backends/drm: fix pageflip events getting lost when outputs get turned off

When a display gets turned off while a pageflip event was still pending, the pending
state gets changed immediately, without waiting for the pageflip event to arrive first.
When this happens, activePending() returns false, and so the pageflip event gets discarded.
This commit changes the logic to only check for activePending() when the pageflip is for a
modeset, avoiding that issue.
