Some times I see such an artifacts. They tend to appear after some inactivity by mouse I would say, it may be 30-120 min period. If to minimize and then restore application window they are disappearing. What is this? Hardware issue? Nvidia drivers issue?

Does this happen in games?

jetigm · December 2020

Didn't tried games, I use my laptop as a workstation for CADs, they run ok and also 3DMark runs ok.

Did this problem occur after any windows update? Have you tried to restore windows to an earlier date than the problem? Does this problem only occur in chrome?

jetigm · December 2020

No. I have the laptop for about 2-3 months, Windows was the latest at that time, then each new update was applied and the problem appears all this period of time, not frequently but still. 80% of cases I saw these artifacts at the Opera browser, but also in Excel few times.

I'm not sure if it will fix the problem. However, there are two versions of the bios referring to the display:

1.08 BIOS doesn't helped. And these artifacts appears at internal and external monitor as well.

does the artifacts appear in BIOS too?

jetigm · December 2020

Never saw them in BIOS but I didn't spent much time in BIOS)

Do you remember the approximate date when the problem appeared?

jetigm · December 2020

Approximately since 2020-11-12.

What happens when you restore windows for October or November?

jetigm · December 2020

Is there any different ways to test the system and figure out what is wrong?

Currently I won't plan to restoring or reinstalling previous Windows builds. The problem don't make my work at laptop impossible, but ofcourse it shouldn't be present in such an expensive system.

Try disabling the lcd overdrive on the predator sense and the g-sync on the nvidia control panel.

jetigm · December 2020

I think lcd overdrive and g-sync are disabled, I even don't have such a settings in predator sense and nvidia control panel and my external monitor don't support g-sync.

The same problem occurs when reinstalling windows, pressing alt + f10 before the acer logo?

jetigm · December 2020

When I installed Windows for the first time, I didn't noticed the problem during installation process and for some days after.

Commodore_1995# · December 2020

OK! But does the problem remain after reinstalling windows again?

jetigm · January 2021

Ok, for about a week from now and after updating nvidia drivers I didn't notice the problem, look like it is gone. I didn't try to reinstall the Windows. If it shows up again I'll post.
