Hello everybody,
i noticed this issue, I see graphical bugs at different time intervals which disappears after a while.
Also noticed that when I right-click on the desktop, sometimes the Font menu is underlined and sometimes not.
I have everything updated.

In GPU Test is everything OK no artefact i did it in 3D Mark,FurMark,Heaven Benchmark.
Also in games is OK.

What i tried?
Different drivers from Nvidia website.
Clear CMOS.
Update BIOS.
Scan system.
Check CPU,GPU,SSD,HDD usage and tempeature and test everything is OK.
Nothing helped.

My spec:
i7 7820x
MSIx299 RAIDER
64 GB RAM
RTX 2070 Super Founders Edition
Seasonic Gold 750 W
Windows 10 1909 Pro 18363.535
