Might help with Windows OBS if you can't hide the Cursor
This seems to let those who cannot hide the cursor to do so, but under "bitBlt" capture mode in OBS. If you don't push the resolution too high, this should work fine.
It seems that some Windows systems running OBS cannot hide the cursor of the electron capture app when in hardware acceleration mode, but some others seem to be able to do so. Not sure what's up there.
