Sometimes Krita will launch in a bugged state, and the only way to fix it is to restart my computer

Support and Advice General Questions
1

OS: Fedora Linux 39
GPU: 6700 XT
Krita Version: 5.2.2 Flathub version and Fedora package version
also tested on
Fedora Linux 38 with an intel iGPU, again with both the Flathub and native versions

At times my Krita will launch in a glitched state - the UI is fine, everything looks OK, but as soon as I click or interact with any part of the application it will freeze for 5+ seconds, then instantly everything I drew/clicked on will happen at once. I’ve had this happen to me on two different machines, it happens with no pen tablet connected and with a pen tablet connected, and I can’t find any reason why this is happening.

Another thing that instantly lets me know if this bug is active or not, is that when I create a new canvas it will appear frozen for far longer than it usually does.

I don’t know if this is related to the bug, but if I run Krita in my terminal, this is what shows up: pastebin link

Sometimes this bug wont happen at all, but as soon as it does, I need to restart my computer to fix it. I might encounter this bug on the first launch of Krita, or the tenth, it’s like a dice roll each time.

If there’s any other info I can provide that might help fix this please let me know, this is my first bug report, thank you!!

Hi, can you reproduce with the official appimage ?

Hi Deevad, I tried the appimage and could reproduce the exact same issue

Ok, good. That’s an easy culprit less on the way.

I’m also on Fedora 39 , but KDE spin and with the Mesa driver for my AMD gpu (a Sapphire Radeon RX 5500 XT 8GB).

Next easy culprits:

  • the GPU driver (maybe test without Canvas Graphic Acceleration in Settings > Display )
  • maybe running Krita on Wayland? Krita is not a native Wayland app, so it runs in a XWayland windows and it is known to inject a layer of specific bugs from what I read on the bug tracker. Maybe test with a log-out, login under a X11 environement and see if it is reproducible.

I disabled Canvas Graphic Acceleration but that didn’t help, however when I logged into an X11 session it started working right away, no more bugs, pauses, freezes or glitches! Thank you so much for mentioning that, now I can work with Krita rather than worrying when it will become sick :heart:
