I've looked into the problem again. I wanted to solve the problem without disabling all GPU features.
I checked the "Graphics Feature Status" with vivaldi://gpu and tried something with the flags.
Only using --disable-gpu-rasterization (or vivaldi://flags/#enable-gpu-rasterization set to disable) fixes my problem. So I can at least use the hardware acceleration for some other features.
Unfortunately, I couldn't find any tickets for this problem quickly. Strange, I'm not the only Linux user with an Intel 8th Gen computer. I still can't tell if this is a chromium problem, or something kernel or archlinux related. If anyone knows anything please let me know.
Thanks 🙂
