Jumping window

I have the game set to run in full screen, while the lobby runs in a decorated window. When the full-screen game window is closed, the lobby window often jumps to the upper left corner of the screen and positions itself in such a way that the title bar is no longer accessible, so it cannot be moved with the mouse.

I used to have both the game and the lobby run in full screen (and the default frameless window at first), but then replay progress is not visible during loading until the screen is clicked. Looks like I just can't win. This is on Win7-64 with an NVidia video card. Haven't tested on Linux.

Is anyone else seeing this? I want the lobby window's jumpjets to be taken away!

Replaced the sdl library from the link in that ticket (SDL2-2.0.8-win32-x86), my window didn't move this time, but it did shrink. So, alas, not fixed.

Never before now. Result: same as full screen, replay does not show loading progress until I click, so back to a regular window it goes.
