Public bug reported:
I have a double monitor setup, my laptop has a built-in 4k screen and my
external is 1080p.
When I use the mouse on the external screen the arrow indicator has no problem
but when I go on the built-in monitor the arrow indicator will blink (disappear
and reappear) every time there is some kind of refresh on either screen (e.g. I
type something or something is displaying text in the terminal).
My current display settings are:
Display Mode: Join Displays
Primary Display: either doesn't make any difference
Built in display:
- Orientation: Landscape
- Resolution: 3840x2160
- Refresh Rate: 60,00Hz
- Scale: 200%
- Fractional Scaling: ON
External Display:
- Orientation: Landscape
- Resolution: 1920x1080
- Refresh Rate: 60,00Hz
- Scale: 100%
- Fractional Scaling: ON
