Short description of error
The UI overlays are heavily flickering, whenever i move anything, it's probably because of the OpenGL drawing stuff
I've tried googling it but i didn't find any helpful workaround to fix it :(
I've attached a short video that demonstrates what's happening.

Make sure you have the latest GPU drivers for you card and test again.

If the problem still exists, please attach the output of "--debug-gpu" and you can also try running blender with "--debug-gpu-force-workarounds" to see if it fixes it.

Additionally try newer blender 2.8 builds. There are new ones released every day with new fixes in them. So in short, update blender version and GPU driver and get back to me.

I already have the latest driver (i checked).

tried to run blender with --debug-gpu-force-workarounds, but still the same problem

downloaded the latest blender build, but still no luck :(
the latest build made things worse actually, now the overlays are barely appearing on the screen

and here is the output of --debug-gpu
debug-gpu.txt

also should i update this post/task to include the updated/latest build info instead of the current one (13-12-2018 build)?

We no longer officially support this card, so won't be dedicating resources to fixing graphics glitches for it:
https://code.blender.org/2019/04/supported-gpus-in-blender-2-80/

Hopefully this bug has been fixed in the meantime though, there were many changes since December.

@ilangut you're most likely on Arch right? There is problem with latest Mesa driver, see #94209
Downgrading to 21.2.5 should work as a workaround for now.

Good to know. I'll just change status to more appropriate one though
