Random freezing issue on Fedora linux

[xaeghn]

Quite a fresh Fedora 40 KDE plasma install and krita sometimes just refuses to work properly. I have tried installing different versions of krita from KDE discover(the flatpak, fedora repo versions) and i’ve tried using the appimage version from krita’s site directly.

Sometimes it works fine but often after the pc has been on for like couple hours it just stops working properly, it opens and loads an image/project but doing absolutely anything completely freezes krita and it just becomes unusable.

I have yet to try X11 session but i’d rather not as it has more issues than wayland for me.

I’ve tried giving all the RAM and tried Canvas Graphics Acceleration on and off, but doesn’t seem to make a difference.

Weirdest thing is that after logout it works fine again after having the freezing issue and I don’t know how to replicate the issue.

Never had issues on Windows 10 side by the way.

EDIT: it seems like it took less time to make it freeze again, about 15min after posting thing I just downloaded something on steam and afterwards it started to freeze again. Checking system monitor nothing is out of ordinary, plenty of RAM available, CPU usage low, etc

Launching the appimage via terminal with just ./krita-5.2.3…etc it yields nothing i see of use just that it says “Requested FPS:” and the number seems to go bit all over the place + it spit out this

Similar experience on Fedora 40 Gnome wayland.

Twice today krita just froze the entire operating system.

Krita is not supported under wayland. It runs under xwayland. So there is not much you can do besides waiting for it to be ported to wayland. Try krita in xorg. Or you can also try filing a bug report for xwayland

Alright good to know that there is no fix currently.

Tried it on xorg and it works perfectly.

Hi, apologies for the bump. Just wanted to say that I think I know at least one thing that may trigger this issue: Steam. If I leave Steam open after some time, either 40 minutes to several hours later, Krita will become unresponsive and freezing like that. If I don’t leave it open, Krita will work just fine throughout the day. I believe another application that triggered it once was mpv, but I’m not 100% sure. The only thing in common between the two is hardware acceleration support. I have disabled Steam’s hw acceleration, I’ll see if it still happens.
