I'm using an Asus ROG Strix G17.
OS: Windows 10 64 bit.
Processor: Intel i7-10750H @ 2.6 GHz.
RAM: 16 GB.
Display: Intel UHD Graphics (For regular display.)
NVidia GeForce RTX 2070 (For games.)
Don't know which video card MWA is using. Probably the Intel, if I were to guess. Unless the game has a program to choose the video card, it's supposed to go with the default.
I initially switched the game to windowed mode, but I switched back to fullscreen when the flickering started happening; in the hopes that doing so would fix the issue.
Unfortunately, that didn't fix the issue. I experienced both the freeze and the flickering in windowed and fullscreen mode.
