SDL3: Screen mode changes causing visual issues, a crash and a monitor disconnect on Linux

[Chiffario]

Type

Crash to desktop

Bug description

Prerequisites:

1. An x11 based window manager (confirmed on awesomewm) or a desktop environment (confirmed on KDE Plasma 6)
2. At least 2 monitors

Steps to reproduce:

1. Change monitor positions via xrandr (seems to work best when swapping them around)
2. Launch osu! in fullscreen
3. Change screen mode to Windowed
4. Change screen mode back to Fullscreen
5. Change resolution to any resolution below monitor's native
6. Change resolution back to native

At steps 3-4 in some configurations resolution reported by the client and resolution of the game seem to mismatch, which causes issues ranging from incorrect in-game resolution to corrupted visual output. At step 6 the monitor the game was on disconnects

Screenshots or videos

Video demonstration (recorded via OBS) and footage of the same issue from an external camera
