Please describe your issue in as much detail as possible:

If the Steam Client window is not in focus, clicking anywhere on the red highlighted area in the screenshot below will cause Gnome to display a standard error along the lines of "A problem has occurred and the system can't recover. Please logout and try again."

You would click on that area if you wanted to bring the window to the forefront or move the window on the screen. I would expect Gnome not to crash and the window to be moveable as per normal Gnome WM decorated windows.

Clicking anywhere else on the Steam client window does not cause this issue.

This issue is 100% reproducible on my system. I'm unclear when it started as it's taken me weeks to track down that this is a Steam issue and can occur when Steam is the only app opened immediately upon login. It is possible that this started when I added a second (portrait) monitor to my system but I can't confirm. This occurs when Steam is on my main (landscape) monitor.

Steps for reproducing this issue:

1. Open the Steam client on Linux
2. Click anywhere on the red shaded area in my screenshot as if you were going to move the window
3. Gnome will crash and you will be forced to logout

Gnome (GDK specifically) closed the issue immediately and asked me to file a bug with Valve.
