I have narrowed down the issue significantly. The revert button stops working if you go from a refresh rate like 2560x2160 59.978424 Hz
-> an even number like 1920x1080 60.000000 Hz
and then proceed to try and use the pop-up to set it back to the original 2560x2160 59.978424 Hz
. The same applies for the other display timings and their relative counterparts. If I try to go from 1600x900 60.000000 Hz
-> 1920x1080 60.000000 Hz
though, then the revert button works as expected. maybe there's some sort of rounding error in the revert logic similar to what we saw with the BOE OLED Deck?
this commit breaks the "Revert" button in the Steam Deck's GamepadUI. After this point, hitting "Revert" after changing a screen's refresh rate/resolution does nothing rather than reverting to your previous good resolution. Tested on both Steam Deck OLED and on my 7900XTX, and this issue happens on both.
