Hi all,

I have a strange problem with my ibook (12" with radeon 9550).

Sometimes I have graphical glitches in program windows and when opening drawers etc.

I made a screenshot : https://www.dropbox.com/s/s2eib0cmh4sg3k3/Window01.png?dl=0

I used to have graphical glitches in titlebars too, but since I set the radeon monitor tooltype
"Sync_bit_blit=yes" the glitches don't appear in titlebars anymore.
It now only happens when I open drawers or in program windows.

This only happens with Morphos. When I use Ubuntu or OSX there are no problems at all.

It doesn't happen all the time. It's kinda hard to tell when it happens. Usually it out of the blue.
It can happen right after boot, or after using the system for a while.

The only way to get rid of them is to set the radeon monitor tooltype "bitmap_cache=NO".
Of course when I use this setting, I can't use any 3D programs or Wazp3D.

It's really annoying. Does anyone have a clue what going on?

Edit: I forgot to mention this is happening with all morphos versions for the ibook (3.2 to 3.10).
And it also happens when I boot from the install CD.

Edit2: I also tried to disable enhanced display, but it only made it worse (it happens more often).

Is that with 3.10? I'm getting changes in screen brightness, it maybe related to the screen brightness changing dependant on ambient lighting, but I don't remember it being that pronounced.

This is on a 15" G4 Powerbook 1.67

Yes, the screenshot is from morphos 3.10. But the problem is there with all versions for the ibook.
