Every now and again when i am working with a jitter OpenGL window i get some really psychedelic graphics corruption going on, which then continues to affect the entire OS until i reboot. This only seems to happen since I upgraded to leopard. Just wondering if anyone else had had similar problems? I am using a 1st gen MBP.

has anyone experienced this in other apps, or is it just with jitter?

i have an early macbook pro with an ATI radeon x1600 gfx card and 256mb ram. i have never had a full screen glitch using max 4 and jitter. i've had some glitches with vade's shaders where parts of the desktop would be captured onto textures. aside from that, i've never had any fullscreen reboot glitches.

i also have max 5 but i'm still getting to grips with it, for important work i still use max 4. but if u can make a reproducible patch i'd be happy to test...

another thing, i'm still using osx 10.4.11

yeah, i didn't have problems with tiger... just leopard, with both 4.6 and 5

yeah i have, but i on ox 10.4.11 using max 5.0.2 on on a laptop.

i was using an open gl patch in full screen on a projector, the visual's on the projector stop working, they did not cut out, they became unresponsive to input , then on my laptop screen where i was controlling the ui from. the laptop screen then Brock down in to about 8 squares that flash will the information that should have been in a different square. i was not a sudden thing, the visual stopped responding, then about 2 mins later, the flashing start on my laptop screen. i had not restarted my computer for about 4 days, the there was alot of other apps open at the time. this has only happen once.

I had the same problem when running a patch with several videoplanes on my 1st gen Macbook pro with an upgraded system (from 10.4.11 to 10.5.5), after I did an erase and install of 10.5.5 I have not seen it again.

This happened while demoing a MaxJitter patch for a dance / video 

built-in iSight with jit.qt.grab and some shader stuff.

i don't remember how it happened (there were for sure max running 

somewhere..) , but was funny / scary enought to worth a screenshot !

these screenshots look just like what happens on my computer.

I tried some openGL demo apps from the developer folder and so far can't get the same problem, so at the moment i assume it is jitter-specific. Will send a report to c74 support.

Exact same look I've had. I've got a first-generation Macbook pro, 

but I think some of my colleagues have had the same problem on other

if anyone can reproduce this consistently, please send a bug report to cycling. Seems to happed sporadically on my machine.

I noticed when i start parallels sometimes i see a similar distortion, but it disappear.

today the latest osx version was released. One of the fixes:

- isn't that what's been going on here?

I had one for the first time the other day, it was aweful, I was in the middle of makign an A/V jam, and it was looking pretty cool. I started to record it with the jit.VCR and the whole screen froze with a full screen frame of really crazy repeated garbled shapes and the computer was totally frozen no response to anything, and I had to hard reset.
