           Summary: [r300g] KWin Lanczos filter problems - Black Windows
                    using effects
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: yafulinux@gmail.com


The issue was discussed in the following entries:

https://bugs.kde.org/show_bug.cgi?id=253483

http://forum.kde.org/viewtopic.php?f=111&t=91027

The problem is referred to certain screens or previews that look black or empty
using effects like "Present Windows", with Gallium 3D (View screen shots in the
second link)
The problem is present using Kubuntu 10.10 (Maverick) KDE SC 4.5.3 (4.5.2 too).
Mesa and ATI drivers from xorg edgers PPA repository:

https://launchpad.net/~xorg-edgers/+archive/ppa

Tested with packages:
libgl1-mesa-dri 7.10.0+git20101104.e7f5d19a-0ubuntu0sarvatt~maverick
libgl1-mesa-dri 7.10.0+git20101108.ef6967dd-0ubuntu0sarvatt~maverick

The problem is also present using Fedora 14 KDE LiveCD wich uses Gallium3D by
default (KDE 4.5.2, Mesa 7.9, Gallium 0.4)

My video card is an integrated ATI x1250 (RS690)
