Framerate drops below 40fps in non-regular intervals

Description

In non-regular intervals and when switching the monitor on, the framerate drops below 40fps, which happens only on the latest hyprland 0.51.0. When this happens, fdinfo shows that hyprland uses almost double the gpu time (25% before to over 40%). After a few seconds or when moving the mouse to a different window, the framerate recovers to 60fps and hyprlands gpu utilization drops to 25% again.
None of the GPU's resources are maxed out at both times (gfx, texture, mem, etc), but the GPU clocks higher when hyprland uses more gpu (that's probably expected).

Setting the displays to 8 instead of 10 bit doesn't resolve the issue. It also happens with both one and two monitors active.

The problem seems to occur only when the monitor has been off and is turned on again. Restarting hyprland when the monitor is on fixes it. Will try to do a bisect soon, as this is really annoying and makes hyprland barely usable.
