@Viktor (Vix) can you still reproduce the bug with the latest builds?

Yes. The latest version I tried was "blender-2.80-0f449541d2e-win64" - 2.80 Alpha Date:2018-07-31 23:01 ...…. and it still crash.

It happens with any of those - 1) I click at the "maximize button, 2) right click at the program window bar and choose "maximize" or 3) drag the blender window to the screen edge to maximize it at left/riht side or fullscreen (Windows "Aero Snap" function) and also by useing standart Windows shortcut "WIn key + Up Arrow".

The result is allways the same - after a slight delay - 1/2 - 1 sec. Blender disappears.

I also tried running blender.exe with "compatibility mode for Windows 8" and also with "disable fullscreen optimizations" checked on and "run as administrator" without luck.

I just noticed that the crash happens also if I rotate the screen from landscape to portret mode (the computer is mobile and support both modes)

Actually, Blender crashes if I try to shrink it's window too ! If I grab the program top-bar and move it around - everything is fine, but the moment I try to make it bigger or smaller by dragging some of the window's corners it crashes.

Unfortunately my other Windows machine is not around, to try it out on it, but when I get it back I will post the results.

Just to say, that Blender is still crashing with the latest 2.80 Alpha 2 version (downloaded on 31.10.2018)
Also, I'm unable to move the Blender window to a second monitor - the moment I try to drag it to the other monitor it crashes and disappears.
The only way to work on a second monitor is to open a new Main window, which automatically appears on my second display.

@Viktor (Vix) did you try updating you GPU driver? another report (T56760) mentioned that updating driver helps and manually disabling CMAA in the Driver's preferences fixed some very similar crash.

Yep! I can confirm that manually disabling CMAA ( "Conservative Morphological Anti-Aliasing" ) in Intel driver's settings is fixing the problem. No more crashing at maximizing and restoring Blender ! 8-)
