Symptoms

Problem with Slitherine launcher:

When clicking the background of the Slitherine launcher (proprietary game launcher/menu) the cursor changes to a hand. The hand then drags the background, you can't right click or cancel moving the background. ALT-F4 closes the entire program.

Reproduction:

Reproduction for Slitherin launcher:

1. Install game trough Steam.
2. Run game trough Steam.
3. Click on the background of the launcher.
4. This moves the entire background when using the mouse.
5. Right clicking or pressing ESC will not help either.
6. As far as I can tell only ALT+F4 will help to close the program.

Tested features:

Start by reviewing the reproduction steps and steam-580720.log, then investigate the launcher behavior described for Fedora 29 with Proton 3.16-7 Beta. Done means clicking the launcher background no longer traps the cursor in dragging mode, while right-click or Escape can cancel it; verify the listed launcher steps and tested features.
