Bit of an unusual issue. I just updated Arch Linux, but I hadn't rebooted in a quite awhile so it might not have even been a recent updgrade.

I'm getting some weird artifacting at the bottom of my screen now. Without a wallpaper it's just a white rectangle: https://i.imgur.com/AZiUUQ8.png

When I have a wallpaper set with feh, there's a tonne of artifacting. It's like my smaller screen is superimposed on my larger screen (the wallpaper isn't suppose to cut-off half-way): https://i.imgur.com/UpU2BD0.png

This artifacting only appears on my "desktop", any applications that are above it do not get the square or artifacting. But when I close the application it is still there on the desktop.

This was working fine prior to me updating, and rebooting.

When I remove my xrandr command from i3's config file, I no longer get this issue (but my screens are in the wrong order).

Here is my xrandr command:

xrandr --output DisplayPort-0 --mode 1920x1080 --pos 1280x0 --output DVI-D-0 --mode 1280x1024 --pos 0x56

If it helps here's some information about my GPU (amdgpu):

[user@hostname ~]$ sudo lshw -c video

Any ideas? I've messed about with my xrandr command for a couple of hours since it seems to be the root of the problem, but I've had no luck. Not sure how an update could have caused this.
