Comment 67 for bug 1870736

The same (?)/similar issue using multi-monitor setup with GeForce GTX 1650 Mobile/Max-Q on a Dell XPS 15.

The screen on the external monitor appears to scale up proportionally beyond the viewport when using fractional scaling, so it is more as if the screen is zooming down into a portion of the desktop/application space.

Once this happens, everything goes crazy. It's impossible to get the screen resolutions back into a working condition without a reboot.

Having just been persuaded that everything's sunshine in the Linux world - after a decades break in OSX - I was so looking forward to the basics just working :-D
