Graphical Glitches on Intel Arc A370M dGPU when using DRI_PRIME=1

I have a ASUS Laptop with an Intel Arc A370M dGPU.
Setting DRI_PRIME=1 and running wayland will make it use the dGPU, this can be verified by running intel_gpu_top

The graphical glitches seem to affect user interface elements, they do not get redrawn when they are updated. For example, scrolling will have ghosting and tearing. When selecting text, the UI doesn't get redrawn until much later.
Windows and UI elements flicker or become invisible. Video playback is perfectly fine.


I am using Wayland and not Xorg so I cannot follow the instructions which require me to use xrandr
This happens on KDE, Hyprland.

EDIT:

On Xorg, this issue is NOT happening!
