Describe the Bug

I run sunshine-git. After upgrading a few minutes ago, I noticed that the resolution was wrong (huge black bars, weird square resolution). In the logs I noticed the following message:

Warning: Mismatch on expected Resolution compared to actual resolution: 1920x2880 vs 2880x1920

This was with commit d157bb1; I then tested the previous, commit 188f1e2, same issue. Commit 2b7af21 is the latest commit that does not have this issue (using it as we speak).

Expected Behavior

Correct resolution used.

I've yanked the latest pre-release from GitHub

[ReenigneArcher]

#4802 is up

Please test if you can.

Glad someone managed to report it before me. I tried last night, and I thought it was the moonlight version I used, so I rolled that back, but then when I rolled sunshine back to the previous pre-release version it was fixed.

Amazing work @ReenigneArcher

I just tested the archlinux build and the screen resolution is correct again :)
