Following an update this morning to one of my bullseye systems, an irritating 
video problem has surfaced. The best way I can think of to describe the 
problem is that if one has a line of black text on what is supposed to be a 
white background, to the right of the text a clear, short tail of even whiter 
background is visible (the tail is maybe an inch or so long).

The update was to:
   Linux 5.10.0-23-amd64 #1 SMP Debian 5.10.179-1 (2023-05-12) x86_64 GNU/Linux

I suspect that this is due to a driver issue related to the update. (I have 
tried a couple of different desktops, KDE and TDE, but they both exhibit the 
problem, so I don't think it can be caused by the desktop software. The 
problem did not exist prior to this morning's update.)

So I'm wondering if someone can walk me through how to figure out what video 
driver I am using, and what other drivers might be available to try?
