Fractional scale: Screen offset for fullscreen mode (games) #62

Closed schluetermichael closed 4 years ago

schluetermichael commented 4 years ago

I've set my screen to 175% fractional scaling (see screenshot) and normal applications just work fine. Display Settings

However if I use an application in fullscreen mode (i.e. steam game) the screen as an large offset (see screen shot). The mouse has no offset and is therefore not aligned to the visible image. Setting the scale to 100% or 200% does not show this problem.

Hi,

This is upstream from us unfortunately and a limitation between xrandr and the GPU driver. What we'll do is make it clearer fractional scaling is ON and advertise it as an experimental feature with limitations.
