The OpenGL Engine was upgraded in ARCHICAD 22 from the previous 2.0 version to 3.2 (which is more recent and efficient). As a result some older hardwares (GPUs to be exact) might not be able to work properly if they don't support this standard, or their driver is out of date.
As I can see you have a 21.5" iMac, but still with a low-resolution display, which could mean that it is a pretty old computer.
Could you check if you get a warning message (a yellow triangle with an exclamation mark in it) in the 'Work Environment > Advanced Redraw Options' window?
Does turning the 3D Anti-Aliasing off (in the same dialog) help?
Could you save a system report file (.spx)
and send it to me in a private message so that I can see what hardware you have exactly?
Thanks in Advance,
