I also noticed the display shrinks / grows depending on the brightness. My original 2/5 does this a little, and my recapped 2/10 does it much more. (Which makes me reluctant to mess with the 2/5...)
My 2/10 has the issue where scroll bars on the extreme right affect the whole display. Setting the h-pos at its extreme left makes this less. At its middle setting, when the system has warmed up, the display can get rather garbled. Adjusting the h-pos will move every-other scan line!

It does not. Those displays are rock solid, there are no analog or
timing issues.
Probably a slightly more modern design.
