Please help: Sudden shutdown of Krita 5

Hello all,

When working in Krita, Krita sometimes shuts down suddenly. I don’t know what is wrong, but I read the log when it shut down. The OS is Pop-OS 21.10 and the version of Krita is 5.0.2.

Thank you for your kind help.

Hello,

You can see at this line:

That segfault is certainly a segment fault. It is some error that is happening to some users under linux (perhaps on Ubuntu-based distros?), which produces these apparently random and unrelated crashes.

You can see an ongoing discussion about it here:
Krita 5.0 is EXTREMELY unstable, constant crashes

On another note. Are you perhaps using an AMD CPU and AMD GPU with the Mesa drivers?

Cheers

Please try the AppImage, if it works on Pop-OS, and don’t forget to make it executable via the file-settings. Other versions and ways to install Krita are often leading to errors.

Thank you very much for your prompt attention.

My system uses the following CPU and GPU

Intel(R) Core™ i7-7820HQ CPU @ 2.90GHz
NVIDIA Corporation GM107GLM [Quadro M1200

I see that another person is having the same problem with their system. It doesn’t sound like something I can solve right away, hopefully it will be an insight for those who are developing Krita. I will keep an eye on the discussion “Krita 5.0 is EXTREMELY unstable, constant crashes”. I’m not using it for business, so I’ll try Appimg or increasing the frequency of backups.

Thank you very much for your prompt response, I will try Appimage.

Hello. I read ”Krita 5.0 is EXTREMELY unstable, constant c rashes 5 https://krita-artists.org/t/krita-5-0-is-extremely-unstable-constant-crashes/39225” and tried two things. First, I did the following to deal with the error that occurs in the Flatpac version. I suspected that this was caused by the firmware not being up-to-date, so I updated the firmware. However, the same error occurred. Next, I tried using appimage, running it from the Terminal to see if there were any errors. So far, no sudden shutdown errors have occurred. However, other errors seem to occur from time to time. I will report back when I have a better understanding of these issues. I would like to thank all those who helped me.
