6. Save scene and add it to Build settings
7. Build & Run
8. On the Resolution dialog, choose non native resolution (different from your monitors)
9. Wait for game to load and quit the game (ALT + F4)

Expected result: Application quits
Actual result: Application crashes

Bug does not occur if build uses DX11

Reproduced with: 5.3.6p6, 5.3.6p8, 5.4.1p2, 5.4.1p3, 5.4.2f2, 5.4.2p3, 5.5.0b10, 5.6.0a1
Not reproducible with: 5.3.6p5 5.4.0f3, 5.4.1f1, 5.4.1p1
