Created attachment 347222 [details] Xorg.0.log With the packages kernel-PAE-2.6.29.4-167.fc11.i686 xorg-x11-drv-intel-2.7.0-7.fc11 xorg-x11-server-Xorg-1.6.1.901-1.fc11.i586 when I start up certain packages such as vncviewer, the screen is corrupted with narrow horizontal bars of colour (in some cases with mixed colour) both within the open window and horizontally across from it. These change as I move this window about, but can be cleared once the window is closed by dragging a different window over the corrupted area. I can't produce a screenshot of the effect because that is also corrupted. This doesn't occur if I boot with nomodeset.
I haven't seen this occurring recently and vncviewer (on Fedora 12) works fine. Hence I am closing this as fixed in the current release.
