interesting that they the bt is pretty near to #371275, but with different backtraces
*** This bug has been marked as a duplicate of bug 370867 ***
FYI: After looking at the related bug 370867, it might be interesting for you that I am using a Radeon RX 480, which is very similar to the graphic card used by the reporter of the aforementioned bug. I am also using the same AMDGPU-PRO driver and have experienced the same behavior as the reporter. I am also using two monitors of different sizes (2560x1440 and 1920x1080). I can crash plasmashell pretty easily by opening an application using Application Launcher and entering the name of the desired application and hitting Enter. It doesn't crash every time, but more often than not.
