Hi DataDrake,

OK, so... the History takeback gave this:

Hi there Serebit!
Thank you for the attention.

OK, I've been testing since the last update of the kernel to 5.5.3-147, torturing Krita and Blender two days long. :)

No problem Jacek. I keep approximately clean and simple linux install. Plus those programs that I use in appimages. So, If something goes wrong with 5.5, I can easily reinstall the system with the old kernel. Thanks.

OK,
After a couple of days of testing I can definitely say that my issue is coming from the new kernel 5.4.12-144.

OK
I did some new tests. The issue could be from the new kernel.

Yep, yep, the test with Solus 4.0 LiveUSB and the appimage was already done. It works fine! :) I did it yesterday with Solus 4.0 Plasma
Yeah, instead of downgrading of the kernel, I think, it would be better if I can find a Solus 4.0 Budgie and do gradually updates and testing to see after which update the crash happens. That will narrow down the causes.

Giving answers as it fallows:

Yes, I suppose the same, but I'm not experienced enough to solve the problem.
Thank you.
