Hello! When launched as a normal user, the usable area of the application occupies 25% of the entire window, and if you run the application from the terminal, QPainter errors are displayed (see screenshots). Reinstalling the app doesn’t help.

QPainter error in terminal:

Hello @vitaly
I’ve deployed Red OS and tried to check out described scenario, but all things are OK:

I installed Desktop Editors via this guide Installing ONLYOFFICE Desktop Editors to Red Hat, CentOS and derivatives - ONLYOFFICE
and I used non-root user to start the app.
I believe you have to focus on your PC as possible cause of situation. Please point me to the guide which you used for Desktop Editors installation. Also please try to reinstall the app one more time, but remove contents of cache folder first: /home/user/.local/share/onlyoffice/desktopeditors/data/cache/

Hello, yes, I myself tried to install on a clean virtual machine, and everything was fine. And I must say, on my computer, too, everything was initially fine, but one fine day it stopped running normally.

I would not want to resort to reinstalling the entire system, and reinstalling the rest of the applications that would be associated with QPainter did not lead to anything.

Have you tried to remove contents of cache folder as I mentioned above? I mean remove contents and reinstall the app after that. Will the situation change?

Yes, that’s right. Today I even reinstalled my system by creating a new user - the error happened again… I don’t know what the problem is.
For now, I got around the problem by switching to another graphical environment - cinnamon instead of MATE. But I don’t think it should be done that way. :disappointed:

We need some to time to re-check the situation. I will update this thread when we have something to share.

Hello @vitaly
We’ve tried to reproduce the issue, but we failed. It seems that the situation is related to your users’ rights settings only since we cannot reproduce it on our test machines.
I’m not sure how exactly we can troubleshoot it or help you.
