What works

Browsing the web 

What does not

Most video playback results in the Firefox tab the video tries to play in crashing. I will get a screen telling me the tab and offer to reload it.

``Unhandled exception: unimplemented function ucrtbase.dll.imaxdiv called in 64-bi

t code (0x00000174013bfe).`` seems to be why Firefox tabs crash when trying to play videos

Hardware acceleration doesn't seem to be working properly either


If I drop in a native ucrtbase.dll file into Firefox's directory and add an override for it, videos start to work.
