I have been noticing a graphics issue since updating to MacOS 11.0, persisting until the current MacOS 11.2 Beta 2 where the screen occasionally fails to redraw after a keystroke when the integrated GPU is in use.
This results in cases where the last character typed (or the results of pressing such key) are not visible until the following keystroke or mouse movement, especially when characters are typed in quick succession.
This issue can reproduced on my MacBook Pro (16-inch, 2019) within a minute or two in the built in Terminal.app and no longer occurs if the discrete GPU is enabled (either by disabling GFX switching or connecting an external monitor.
