REVISION SUMMARY Under wayland we support high DPI putting by putting a separation between the logical co-ordinate system and the resolution of rendered assets. When a window is on a high DPI screen, we should render at the higher resolution. Like the window scaling this handles any combination of a 2x scaled decoration being rendered on a 1x screen or vice versa. --- This patch is a bit different from the other scaling stuff. We have to generate the quads *before* we have an updated texture with the new scale. This means the scale isn't attached to the buffer like elsewhere. That's why I added a property in TopLevel so there's still one canonical source and things can't get out of sync. BUG: 384765 TEST PLAN Crystal clear breeze and oxygen decos on my @2x display Drag windows to attached @1x display, things still look OK when across 2 screens Changing the scale of a screen updated the decos instantly REPOSITORY R108 KWin BRANCH master REVISION DETAIL https://phabricator.kde.org/D8600 AFFECTED FILES decorations/decorationrenderer.cpp plugins/scenes/opengl/scene_opengl.cpp plugins/scenes/qpainter/scene_qpainter.cpp plugins/scenes/xrender/scene_xrender.cpp scene.cpp scene.h toplevel.cpp toplevel.h To: davidedmundson, #plasma Cc: plasma-devel, kwin, #kwin, bwowk, ZrenBot, progwolff, lesliezhai, ali-mohamed, hardening, jensreuterberg, abetts, sebas, apol, mart
