I'm facing a graphics bug in my emulator (https://github.com/barotto/IBMulator) where a part of the framebuffer is not correctly rendered.
Here is a demo of the problem: https://imgur.com/a/XFDtR
I suspect this issue https://github.com/barotto/IBMulator/issues/9 with Rocketeer could be caused by the same bug.
My understanding of the VGA hardware is limited and frankly I don't have any idea of where to look for this bug.
Do you have any suggestions?
What's a good book about the VGA that explains its inner workings in good detail?
IBMulator shares a lot of code with Bochs and this same bug is present on that emulator too.
If I'll find and fix this maybe I could send a patch upstream.
