Hi, I just recently installed EndeavourOS with KDE Plasma. Whenever I open a fullscreen application on my secondary monitor, it goes black. I believe it’s based on mouse movement, as after it sits for a while without moving the mouse, it turns back on. Then moving the mouse makes the screen turn back off. This happens with going fullscreen in Discord, firefox, and reddit videos. The secondary display is an Acer XF240H 1920x1080, and the GPU I use is an AMD Radeon RX 7600XT. This only happens for the secondary monitor, not the primary one.
Experiencing the same problem. I’m using a ThinkPad E14 laptop with a Ryzen 7 CPU and integrated Radeon graphics, connected to an external monitor via HDMI. It all started about a week ago after a Pacman update.
Any ideas on how to fix it?
