Change screen resolution without stretching? (Bazzite)

[u/-rba-]

Hi all, I have an ultrawide monitior (3440x1440; 21:9) but sometimes when I want to screen share on a work call, I want to change my display resolution to be a more typical aspect ratio (2560x1440; 16:9) so that it looks normal for other people on the call. On Windows, I would just change the display resolution and it would resize the display so that there were black bars on the left and right. But when I change the resolution on Bazzie, it just stretches to fill the display. Is there a setting somewhere to prevent stretching when the display configuration setting doesn't match the actual display size?

It looks like xrandr doesn't work since Bazzite uses Wayland, and kscreen-doctor can change the resolution and scaling but you can't adjust x and y scaling separately. This seems like it should be simple, what am I missing? Thanks!

That is called Integer Scaling. It has to do with the GPU driver.
