@Mugen87 Could you just confirm, but I think it would be better to revert it again if the problem was related to this #31423

[Mugen87]

#31423 just fixed the color space issue.

The revert of #31361 fixed an issue that looked like a mismatched resolution to me.

It's best if you checkout a branch with the commit from #31361 and compare with prod.
