Description David Edmundson 2015-07-25 16:44:05 UTC 
Panel struts to X are wrong when using QT_DEVICE_PIXEL_RATIO=2

Qt lies about the screen size, we tell kwin the wrong positions and then we get windows overlapping the panels

Handle clients having a different device pixel ratio

Qt scales down the size of QScreens by the device pixel ratio; we should
make our windowing APIs match.

X (and KWin) deal with device dependent pixels, so everything needs to
be converted when communitcating geometry.

Abstraction happens in the main kwindowsystem so X and Wayland are both
supported.
