Since MorphOS 3.2, my Powerbook 1.67 Ghz does a strange graphic bug starting it.

the bug

I have just to reboot to get my normal screen like that

This bug happened 3 times and I started ma machine less than 10 time since update.

I sometimes get some, or sometimes a full page of grey distortion, and I have to reboot my powerbook it's always done it with 3.1, but with 3.2 does see, to be worse. 1 in 10 boots with 3.2, about 1 to 20 for MorphOS 3.1

I get the same problem. It happened much more frequently with 3.1 but still quite common with 3.2.

I get this crashed boot screen about 1 in 10 boots, where the colours on the screen all kind of cross fade with each other and a 5cm horizontal grey bar appears at the top of the screen.

Me too!

Same problem for me.
I've heard it's a known bug at the development team

Same for me. But only occationally.

On my Powerbook 1.67 With MorphOS 3.1 I usually get my desktop trached very often.
Now with MorphOS 3.2 it has only happend ONCE in about 50 boots.
The Boot screen get trached often but the screen is fine when Ambient loads, so for me it's working great after the update.

One thing that may help those with big problems, hold down "Alt"-key while booting and then select your MorphOS boot partition.
This thing helped me alot with MorphOS 3.1 to get my wireless router connected at boot time and I'm not 100% sure but I believe I got less trached screens aswell.

A BIG THANKS to all MorphOS developers for all your hard work!

+1

also some 3D blankers seem to crash the powerbook after a while (eg : the feathers one).

I've been playing with Linux on the same machine and this same graphics corruption happens when Xorg starts about 50% of the time too.

The interesting thing however is that when this happens with MorphOS the machine hangs and doesn't complete the boot process but on Linux the corruptions is visible for about 10 seconds and then it vanishes and the desktop is displayed as normal.

Just thought I'd update this thread incase Frank or Mark read it and could maybe look at the Xorg radeon driver for some clues to fix this on MorphOS?
