Created attachment 150125 [details] Screenshot 3 Third issue: Sometimes FF's window is rendered too low in a VD, only showing the tab bar above. If it's moved then, it shows the window far below the dragging cursor.
Created attachment 152811 [details] Screenshot: 5.26.0, Thunderbird Something similar happens to thunderbird: The window is not painted correctly respectively, it seems it painted off the screen.
Since I cannot reproduce this particular issue for the Firefox browser, I will reopen one for the Thunderbird issue.
