What are your computer specs?
Intel Core i5-8400
16 GB RAM
64-bit Windows 10 Pro
Another thing that you can try is disable hardware accelleration in settings>about.
I turned it off and relaunched, but the same thing happened.
If I try to type anything into a note after the screen has become unresponsive, then that text does show up once I close the app and reopen it. I tried this with hardware acceleration on and off, and it happens in both cases.
I’ll try some more Electron apps and will make a screen recording later today.
