[fairydust] switching between DP-alt-mode monitors results in wrong screen arrangement #474
Description
I'm using fairydust (commit 61b6e71) with a pretty standard Fedora 42 Asahi Remix.
The DP Alt Mode works very well, but when going between my home and office desks (which each have an external monitor of different resolution) the multiscreen "arrangement" doesn't adjust properly.
When switching from the small screen to the large screen, the arrangement has the screens overlapping.
When switching from the large to the small screen, the arrangement has a gap between the screens.
The workaround is to go into KDE System Settings -> Display Configuration -> Edit Arrangement, and then drag the arrangement into something reasonable each time.
Maybe this is more of a KDE bug. However this problem only occurs for me when using DP Alt Mode. If I use these same monitors on the HDMI port, the arrangement reconfigures as expected.
