Weird colorful pixels after turn display on

[mateusvahl]

My computer turns my display off after 15m of inactivity,

After start using my computer again, vscode starts to display some weird pixels over file tree and terminal(maybe because they do more heavy work?)

I also happens sometimes on my google chrome, so I believe its related.

Maybe related, but not same:
