Results window opening in random positions

Hi,

I have an annoying issue with DataGrip. Since I once tried out the different positionings of Query-results windows, they now appear in completely random positions.

Once, I changed the position to the right side (split view) and once I tried windowed mode. I didn't like the positions and changed back to normal (docked mode, left side). Now, 1 in 10 queries appears either in right docked position or windowed position, completely random, which is pretty annoying. Please investigate. Version is 2018.2 (cannot upgrade at the moment because of GIT plugin).

Thanks!

Michael
