Strange UI/gamewindow bug

Hello. I cannot find anywhere something about it. Can someone help me fix this issue ?

Sorry for quality but had to record with phone. It`s happening random time. I just show example of this issue . Sometimes happen when large group of mobs/effects appear and sometimes just normal time. Not only UI dissapearing. Whole game window for short time.

Someone maybe had similar issue ? Know what is a reason of this ? Thanks for hlp.

Sorry for english

Forget to add.. I play with Glide :

settings tab: only desktopresolution check and 60 HZ
Renderer tab: texture for videos and shader-gamma check
Extensions tab: everything check

What did you mean whole game window? It flickers like UI or game is just crashing to desktop?

And have you tried Direct instead of glide?

Okay so i just fixed it. I just uncheck last box in Extensions tab and reproduce this few times in place where this happen often and no issuse`s.

Sory for topic before checking alone.
