          Priority: medium
            Bug ID: 69543
          Assignee: dri-devel at lists.freedesktop.org
           Summary: Radeon EXAPixmaps don't work with stretched XRender
                    pictures
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: jujibo at gmail.com
          Hardware: Other
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Radeon
           Product: DRI

There is garbage on screen with some stretched XRender pictures with radeon
driver and enabled EXAPixmaps, see for example MSEide without xorg.conf

http://sourceforge.net/projects/mseide-msegui/

MSEgui uses stretched one pixel width or height pixmaps in order to draw linear
color gradients. 

If you add Option "EXAPixmaps" "off" in Section "Device" of xorg.conf display
is OK but performance falls.

Same problem using NOUVEAU driver. I can't figure out how disable EXAPixmaps
for nouveau driver.

Reproducible: Always
