Comment 2 TraceyC 2026-04-14 19:24:28 UTC 
Sentry has 29 events and 6 reports. Setting to confirmed.
Comment 3 Vlad Zahorodnii 2026-04-20 07:47:46 UTC 
I am unable to reproduce the crash. Did you change any plasma settings? Can you please see if changing some options "fixes" the crash?
Comment 4 Eugene Shalygin 2026-04-20 07:49:57 UTC 
It might be that the trigger is the vulkan plasma rendering backend.
Comment 5 Bug Janitor Service 2026-04-23 09:14:40 UTC 
A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/9133
Comment 6 Vlad Zahorodnii 2026-04-23 12:15:49 UTC 
Can you please apply that patch and check whether kwin still crashes?
Comment 7 Eugene Shalygin 2026-04-23 19:02:54 UTC 
Sorry, I can't. Did not use my home PC this week, and now plasmashell freezes on start for 30 s, as if there is synchronous network request running, and I can't make it crash anymore. Will try more experiments on the weekend.

Delete windows later

After finishing a frame, the SurfaceItem will attempt to clear out a
fifo barrier, if there is one.

On the other hand, when a surface is unmapped, the Window will be
deleted. An effect can extend the lifetime of a window. If there is no
effect, however, the window will be deleted immediately.

If a window is deleted, so will be destroyed the corresponding
WindowItem tree.

It can happen that when the SurfaceItemWayland::handleFramePainted()
calls SurfaceInterface::clearFifoBarrier(), it can apply a commit that
unmaps the surface. If there is no effect that references the window,
the SurfaceItem can be immediately destroyed. This is a big problem
because the SurfaceItemWayland::handleFramePainted() has code that
accesses the SurfaceItemWayland data after clearFifoBarrier().

This change postpones the deletion of the Window so the SurfaceItem is
kept alive if the associated surface has been unmapped.

Another option is to clear fifo barriers when not traversing the item
tree. It will work but introduce a new set of challenges, like ensuring
that the Transactions are always valid. Also, maybe delaying the
deletion of Windows is worth it after all, it's not the first time we
hit a problem caused by windows unexpectedly getting deleted too soon.

Temporarily reference Windows during compositing

See bf961f7fc3b3a86e079ebfa4637c64fb8fb6ebd8 for more explanation. The
reason why that commit cannot be backported because it depends on

Temporarily reference Windows during compositing

When a fifo barrier is cleared, a window can be unmapped and the current
SurfaceItem can be destroyed.

In order to prevent use-after-free issues, this change makes the
workspace scene reference windows during compositing. We need a better
fix in long term.
