Extreme flickering / black screen in fullscreen mode in 1.8

[sndrtj]

Hello there,

In 1.8, I get extreme flickering and entire periods (seconds / minutes) of black screen when I am in fullscreen mode. Between the black screen periods, my monitor will usually return an "input not supported" message. It makes KSP unfortunately completely impossible to play.

I've tried disabling V-Sync, lowering the resolution and lowering the refresh rate on my monitor. None of this works.

However, running KSP in Windowed mode works like a charm, without any of the aforementioned flickering and black screens. I would be OK with this if -popupwindow worked, but that also seems to activate fullscreen mode (tho ''fullscreen" gets unticked in settings), with all its associated problems.

Downgrading to 1.7.3 completely alleviates the fullscreen problem. 

My specs:

Windows 10, 64 bit.

64-bit KSP, installed through steam, version: 1.8.12694 (en-us)

AMD Ryzen 5 2400G, with Radeon Vega 11 GPU.

16GB RAM.

AOC GV2460V Monitor, with default refresh rate of 75hz.

Player.log on fullscreen 1.8 can be found here (expires in a week).
