Hi,

I have tested a very simple Qml app (red rectangle) with weston + qtwayland (5.4.1) and see now a graphic issue when resizing the window to the top or bottom of the screen. 
I run the Qml app with: /usr/bin/qt5/qmlscene -platform wayland-egl test.qml

window with graphic glitch:

window without glitch:

The glitch doesn't appear all the time when resizing the window. After some resize steps its gone and after some more resize steps it is visible again, and so on ...

Did anybody see such graphical issue with weston + qtwayland too?


Cheers
