Fractional Scaling Hackfest

Taipei, Week of 5 June

Relevant GNOME team

(!) Gnome-Desktop Team


(!) GNOME shell has supported hi-dpi monitors for while. Currently, we only allow to scale windows by integral factors (typically 2). This proves somewhat limiting as there are many systems that are just in between the dpi ranges that are good for scale factor 2, or unscaled.

We want to support different fractional scaling values in mutter and gnome shell, by upscaling the widgets and then downscaling to the requested value at composing time.

Agenda, goals

* Drawing the Shell UI at a higher resolution than what the logical pixels correspond to.

* Non-integer scaling adaptations here and there

* Xwayland clients support study
