Whole map is visible and flickers / major graphical glitches

Sometimes when a lot of action happens the game freezes for 1-2 seconds and then all the map is visible and flickers. In worst case scenario game completely glitches and all the textures turn pink/green and flicker like hell, however it happens in 1/10 cases, usually it's only the map that glitches. Only rebooting the game helps.

Drivers are up to date.

I closed browser and PoB, freeing up a lot of RAM and this bug now happens more rarely, but it didn't happen before 3.12 at all regardless of how much other programs are running.

UPD: also some vfx textures just turn into a half transparent squares (screenshot 3). And in my passive tree I noticed (screenshot 2).
Just loaded into a fresh map (screenshot 4)


Win 10

8gb DDR3
GTX-750TI
120gb ssd, 23gb of free space

UPD: switching to dx11 instead of vulkan seems to fix the issue, at least for now. Gonna play for some more to see if it fixed it for good. Also added --noasync to steam launch options just in case.
