The final "composing" step in Wayland does require Wayland to use a "giant" buffer as well. Also My GPU has 16 GB of GDDR how can any frame buffer be "giant" in

The final "composing" step in Wayland does require Wayland to use a "giant" buffer as well. Also My GPU has 16 GB of GDDR how can any frame buffer be "giant" in that context?
The support of hidpi scaling is something Toolkits have to manage (on both Wayland and X11). On X11 all the necessary pitch information to do so is available via the xrandr extension.
- md8z 5y agoYou really don't want to use Xrandr information to do scaling, it's not accurate. A better way would be to set a property on the window and have the compositor read that, AFAIK this is the solution that the Kwin developers were working on.
