Save Online dialog gray after minimizing
If I minimize the Save Online dialog, or switch desktop so that it is no longer visible, then it goes gray when I maximize it again and the controls are no longer visible.
Workaround 1: The problem does not occur when I bring a different application window above the dialog, such as by the using Alt+Tab shortcut to switch between running applications.
Workaround 2: After the problem occurs, right-click on gray dialog > View page source. Right click again > Back.
Regression: This problem did exist in 3.4 but has not always existed (not a recent regression).
I'm using the AppImage
OS: Ubuntu 19.04
