Strange Blender UI Error

I took a little break and came back to blender and started following old tutorials.

but at random when I make an adjustment the viewport will freeze. I can still move my mouse and change settings in the side panel however the viewport stays the same…

then I thought about changing the window size of the viewport, and when I did that I got some rather artistic failures.

Then This one:

The application saves and closes fine, and upon restart returns to normal. But every 5 flippin seconds I run into this, and it is getting a little old.

I am on an Ubuntu-like Linux computer with 16 core CPU (no gpu) and 16GB of ram.

I can’t think of any way this can be reproduced, but it has occurred even after a complete wipe of blender from my machine.

June EDIT: Since this thread still has all relavent info I figured making a new one would be pointless/spam.

Came post graduation, decided to finally start this up as a regular hobby but landed flat on my face with this same wall.

I have pretty much same stuff, swapped to Kali linux(complicated, but its what I got)

Versions that don’t work for me that I’ve checked are 2.93, 3.6, 4.0, and 4.1

Same symptoms, scene hits a certain size and every few actions, I hit the black viewport again. Change viewport window size and it bugs the heck out. Go to another page like sculpting, and same issue.

Honestly I expect this to be a hardware issue, but something like that is going to take a more bountiful funding than I’ll have for the next year or so, as I’ll just revamp my set-up for something like that.

If its a fix that may/ maynot work, I’d still like to hear the thought process.
I will be switching to something like Fedora here soon, so if that looks prosperous I’ll edit post on it.

It may be a GPU driver problem or a hardware problem if it is serious.
(They say they don’t use GPUs, but it’s GPUs that organize and show scenes in blenders.)

If you’re using blender 4.0, and the problem persists, use blender 3.6. The OpenGL version has increased since blender 4.0, and even if the GPU meets the requirements, there are some problematic drivers.

Giving this a shot right now, so far so good. Not much functionality that I need from the later versions but it does suck for people like me with no GPU :sweat_smile:

Thank you so much for the info, lots I didn’t know here!

blender 3.6 is a long-term supported version and is also file compatible with blender 4.0.
Blender 3.6 might be better :slightly_smiling_face:
