Comment 5 for bug 1553428

Same here. It seems to be related to screen resolution/window size.

On my native Laptop screen (1280*800) everything works.

Put the window on external screen (2560*1440), the freeze occurs when zooming out max with maximized window.

If the window is only 1/2 of the screen size, there is no problem.
Zoom out & Pull the window to 3/4 of screen size -> freeze.
