Using the "nv" driver, this problem does not manifest, however the performance is positively abysmal, i.e. takes a second or more just to redraw the screen. I can concede that this might be an nvidia driver issue, however it should be noted that this problem does not happen (with the same nvidia driver versions) in RHEL3 or RHEL4.

After scrolling down (with the scroll wheel) several rows then scrolling back
to the top. Note that the rows are completely garbled.
I found a resolution to this bug on the nvnews.net forums: http://www.nvnews.net/vbulletin/showthread.php?t=50434 Turns out the problem is with the interaction between the Xorg server and the accelerated nVidia driver when the "Composite" extension is enabled. Disabling the Composite extension fixes the issue. However, I'm not sure if this is something the Red Hat folks need to work on, or nVidia, or both. To disable the Composite extension, add these three lines to xorg.conf: Section "Extensions" Option "Composite" "Disable" EndSection The redraw/repaint problem does not exist with rdesktop-1.5.0-1.i386. I obtained this from the FC6 updates and installed in my RHEL 5 Beta2 installation. Another work-around to this problem is (for tcsh): setenv XLIB_SKIP_ARGB_VISUALS 1 An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2009-1417.html |
