Have you tried the native Zen instead of flatpak ? Looks like Zen can't use your NVIDIA GPU at all

Did you install the optimized version of zen or the generic one

Similar problem here. I already reinstalled to clarify. Yes, I'm using the Optimized version, and it's still stuttering when scrolling. I also tried the UFO test site with my 120hz monitor, it just wouldn't keep up on some other tests, especially compared to other browsers.

The last version doesn't have this issue.

To me this issue it feels like this issue was introduced in the latest a.14. I'm using the optimized build on Windows on two machines and it's very noticeable even when scrolling since two days.

Does it get better once you disable zen.view.experimental-rounded-view in about:config?

Manut38 commented 6 hours ago

@mauro-balades YES! It does. It still feels like its more laggy than previous builds but that might be just negative placebo by now 😁 But the big lag spikes that occurred all the time are gone when I disable this setting. What does it do? The web view is still rounded, even when disabled, or does this toggle something different? Thank you!
