From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.5 (X11; Linux i686; U;) Gecko/20020809 Description of problem: Vhen using gtk+1 apps the screen becomes corrupted. It looks like it's "dirty". That I first thought it is so I carefully cleaned the screen, but it was not the case. Cofee-coloured lines appear especially at the end of the windows. The corruption dissapears only on cold reboot. Version-Release number of selected component (if applicable): How reproducible: Sometimes Steps to Reproduce: 1.Start an gtk1 app (galeon). I can always reproduce it using gcvs from www.wincvs.org 2.The screen becomes corrrupted 3.The problems becomes worse in time. Actual Results: Cofee-like colured dots and lines on the screen, especially at the end of the windows. The corruption becomes worse in time. Expected Results: No corruption Additional info: Using latest rawhide packages. (20020823) The machine is an Toshiba Satellite Pro 4300. I am also using the framebuffer with "vga=791 video=vesa:ywrap,mtrr" as kernel parameters.

This is probably a video driver issue, and not likely a GTK problem, however lets not rule out anything until we know better details. Can you add the following to the Device section of your X config file: Option "noaccel" This is to test if it is a 2D acceleration bug or not. If this option makes the corruption go away, update the bug report letting me know that, and we can then try some other tests to narrow it down, without losing too much performance.
No, disabling 2d acceleration does not help. I can see the windows drawing slower but that's it. Starting galeon and shuffling around the workspaces and moving the galeon window makes the corruption reappear.
Please attach a few screenshots showing this problem.
Odd. If I create an screenshot and view it on another machine it looks ok. I'm beggining to suspect bad video ram or some other hardware problem.
One more note. Now if I close all the windows in an workspace the corruption dissapears. (Maybe because of screen repainting ?)
Does disabling acceleration change anything? This sounds like a gtk issue to me, or a buggy gtk theme. It may be hardware issue possibly like you suggest above as well. The software 2D code in X has been around for ages and it functions identically on all hardware. If you've disabled 2D acceleration and still get this problem, then I doubt it is XFree86 related. It's been a while since this was reported. By any chance have you observed any changes, or acquired new data to update the report with before I change status?
