From Bugzilla Helper: User-Agent: Mozilla/4.79 [en] (X11; U; SunOS 5.8 sun4u) Description of problem: When using the r128 driver in the Xfree 4.3.0-2 package on Redhat 9 screen 'noise' can been seen as a vertical bar 1/4 from the right side of the screen the desktop background when moving a window around on the screen. Removing DRI from the X config does not solve the noise. This problem does NOT happen on Redhat 8.0 with DRI ON or OFF. This appears to be a bug in Xfree 4.3.0-2. This is a laptop with an ATI r128 Mobility M3 chipset. The hardware is fine, but Xfree appears to be broken. Version-Release number of selected component (if applicable): 4.3.0-2 How reproducible: Always Steps to Reproduce: 1. Start x 2. Move a window on the screen 3. Actual Results: The screen noise appears 1/4 from the right side of the screen Expected Results: No screen noise Additional info: Happens with stock Redhat 9 kernel and Xfree-4.3.0-2
Just a speculation for now, but it sounds like perhaps the timing is off on something in the driver. Please attach your X server log file and config file to the bug report using bugzilla file attachment. I do not have laptop hardware, however I do believe I have a prototype Radeon M3 engineering sample somewhere. In order to maximize the chances of someone being able to investigate this problem, figure out what is causing it and hopefully be able to fix it as well, it would be a good idea to file the bug report upstream in XFree86's bugzilla at: http://bugs.xfree86.org and then paste the upstream URL here so I can keep an eye on the upstream report as well. Thanks in advance.

You are not using a Red Hat kernel, and while this bug probably does not have anything at all to do with the kernel, I must ask you to please reproduce it while booted into the official Red Hat Linux kernel, and attach your newest X server log. While it is unlikely to make any difference, there is a remote possibility of something, and we only officially support systems which run the binary software we supply.
