Hi,
I got crash whem maximized window is minimizing in the official 4.7.1, reproduction steps:
- download 4.7.1 official build
- create a sample project with some materials, in my case I created FPS sample with starter content
- open content browser
- press F11 to maximize main viewport
- open material editor, the material editor window will slide under the main viewport
- press F11 to minimize main viewport and observe the crash
