Description simplelinuxuser 2020-12-20 03:34:50 UTC

plasmashell 5.20.4
qt5-qtbase-5.15.2-2.fc33.x86_64

When on wayland applications crash when heavily loaded.

This happens for me with clementine importing a big library or dolphin opening a big folder (100.000 files), during that time I am trying to resize it.

The easiest way to reproduce is:
1) Open a terminal.
2) start dolphin/system settings/clementine/kwrite
3) press ctrl - z
4) try to resize the application
5) write 'fg'
6) application crashes

Cannot reproduce.

Qt 5.15.2 is before the callback refactor, which could be related. 


Please include stderr of the crashing app with your steps.

I did some further researching and this might be it:
https://gitlab.freedesktop.org/wayland/wayland/-/issues/159

It basically says that any application on wayland will crash this way.
Either via (ctrl-z) or if an application does stuff (dir loading, big file loading)

At least there is X11 still (which has some other issues for me).

Oh well :(

New information was added with comment 2; changing status for inspection.

Indeed I remember that clients get terminated, if they don't answer Wayland pings regularily.

Comment 5 David Edmundson 2021-01-09 18:06:24 UTC

We can't do much with the information given. 

I would assume it's running out of IDs which the callback refactor fixes
