For a bit of background the problem is related to this posting at:
http://www.amigans.net/modules/newbb/ ... hp?topic_id=3670&forum=28Though at first reverting to the old graphics.library.kmod seemed to work I just hit a situation where the problem did not occur. It still did get it on later tries, which was what I was wanting to confirm.
I have tried your suggestion of rolling back the ATIRadeon.chip now. This does seem to have worked, I cannot get the broken line drawing to occur again, no matter how much I try.
The problem was missing lines, truncated lines pointing in the wrong direction and also some lines were split. I will be able to email you a more detailed description with screenshots later tonight.
Rolling back both kickstart files seems to have fixed it for now but I will keep on testing just to make sure. Whether it is solely the ATIRadeon.chip or a combination of both I can try out too. Or will the new graphics.library.kmod rely on having the newer radeon file ?
Thanks for the help so far, if the line drawing in OS4.1 update 1 is in need of fixing we can try and work out what is happening.
