Public bug reported:
This is on a legally blind user's machine so a larger cursor is needed.
Had problems on problems on ubuntu 20.04 n optiplex 780 with G98 [GeForce 8400
GS Rev. 2] with largest size and Yaru cursor. Cursor was flickering and a
square region around the cursor often failed to update.
nvidia-settings -> x screen 0 -> open gl setting enable flip off and
quality=high quality helped. Changing cursor in gnome-tweaks appearance themes
cursor from Yaru to the smaller redglass helped more. Changing it to DMZ-black
steem to help more. But the region around the mouse cursor is still not
updated. So, for example, what you type does not appear if it is behind cursor
rectangle.
Current state:
- cursor not flickering
- area around cursor often not updated.
- system nearly unusable
Display driver had already been changed from open source to nvidia
proprietary to deal with other display update problems.
