I couldn’t find this in the archives, and unfortunately it’s a 4.6
issue (I don’t have easy access to an iMac to test it under 5 yet). I
have a standalone application that uses jit.desktop at one point,
updating the output every 2 seconds. It works fine on all kinds of
platforms — various Macs and Windows machines — except new iMacs
with large screens. For some reason, it seems that jit.desktop pumps
the CPU usage up to a sustained 100%(!) usage level.
One thing I’m doing is to reduce the Desktop image to a 60×60 matrix,
i.e. [jit.desktop 4 char 60 60]. I tried reducing the screen
resolution on the iMac, but it seemed to have no effect. And again,
this problem only seems to manifest on new iMacs. Has anyone else
encountered this? Any suggestions?
