Screen "flickering" in browsers and under load

[MarcHover]

Hello, i just recently received my cosmo and noticed a strange behaviour. When i am in a browser, Chrome or Brave to be exact, i often get a screen flickering patern when i change pages, i have the feeling that it has got something to do with the processors load.
Has anyone else expearianced something like this, and who can i get rid of it?

I confirm this behavious, however in my case it is not a screen flickering, but the background picture momentarily appearing when switching apps - I am using the KISS lancher with a black background, but the original picture is still there unchanged.

I guess setting the background  to a completely black PNG would help (but so far I could not have been bothered). Or even this: https://github.com/rocboronat/null-black-wallpaper

No i think what i have is a diferent kind of issue, its a patern like effect all over the screen. I found out that turning the "disable HW Overlays" setting in the developer settings on fixes the issue. But i am not satisfied whit this, because firstly it has to be set after every reboot and secontly it drains the battery faster.

Yep I get a few vertical bars on the right hand side of the screen. Was worried about lose cables at first but I don't get it very often and haven't seen it in a while.
