You might want to try good old qtrle: rle is good for repeated pixels,
and qtrle has the ability to code "following N pixels come from previous
frame", which makes it good for screen capture. Not sure how it
compares these days, but 10 years ago it was still one of the best
options for screen capture iirc, esp. with low color depth (8 or 16bits
per pixel).
