Bug or Regression?

Regression

Description

Using Firefox on my 2nd (secondary) monitor was unusably slow. Typing in the search bar, playing videos etc. had huge lag. When I switched to first monitor the problem disappeared. When I rolled back from b0861b6 to latest commit in tag 0.39.1 the problem on the 2nd screen vanished.

How to reproduce

When using Hyprland b0861b6 with 2 monitors attached, open Firefox on the 2nd (secondary) window and use it in a general way, watch Youtube, browse etc.

Crash reports, logs, images, videos

No response

it's 0.40 xD

Anyways, since this is a regression (even though you marked it wrongly as a bug) please do a bisect: https://wiki.hyprland.org/Crashes-and-Bugs/#bisecting-an-issue

I can do the bisect. Yeah the perf dropped so drastically I figured it's a bug, thanks for correcting.

I realized I had built from main from commit b0861b6, I have updated the issue accordingly.

Is not slow, for some reason firefox only refreshes when the cursor moves or when another application in the same monitor redraws itself.

Can confirm, happens to me too. Last working commit is e4e8406

For me, this only happens when I fullscreen firefox (maximize and fakefullscreen works fine)

I experience the same behavior.

Can anyone check if #6010 fixes the issue?
