[Bug] WM breaks when screen turned off due to inactivity using multiple displays

[levkk]

Description

Let me preface this by saying I'm running the nvidia proprietary driver and an ultrawide screen in PIP mode (picture-in-picture), which simulates having two displays. One is connected with DP and the other with HDMI, both connected to the same screen and my nvidia card.

When the screen is turned off by the power manager after some inactivity, the window manager blows up. When the monitors are turned back on, one of the displays is broken and the other stops rendering windows correctly. When windows are moved around, they create this "replication" effect, where instead of moving the window, parts of it are copied into the direction of the move. I don't have screenshots of this since the WM is not usable.

Budgie version

budgie-desktop 10.9.1

Operating System

Arch (6.8.9-arch1-2 #1 SMP PREEMPT_DYNAMIC x86_64)

Steps to reproduce the issue

1. Let the monitors go to "sleep" after some inactivity.
2. Wake them up with a mouse movement or keyboard.

Actual result

One of the displays is black, the other isn't rendering windows correctly.

Expected result

Both displays working just fine.
