stair-stepping in gnome-terminal on [RV280] with llvmpipe

Description John Reiser 2012-03-29 18:15:57 UTC
Description of problem: llvmpipe renders multi-line text panes with a window pitch [logical  width in pixels] that is about 32 pixels too small.  The result is unreadable stair-stepping "down and to the left". The bad rendering appears for gnome-terminal, gedit, the drop-down list from the address bar in firefox, etc.


Version-Release number of selected component (if applicable):
mesa-dri-drivers-8.0.1-7.fc17.i686

How reproducible: every time


Steps to Reproduce:
1. Run Fedora-17 Beta RC2 on i686
2. Force llvmpipe rendering, for instance by
  # mv /usr/lib/dri/r200_dri.so $HOME
on a machine with Radeon 9250 [RV280] (pci 1002:5960);
then log out, then log back in to restart X server.
3. Invoke gnome-terminal.
  
Actual results: "Stair stepping" down and to the left, as shown in camera shot. [Screen shot did not work.]


Expected results: Correct rendering.

"glxinfo | grep renderer" says:
    OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300)

If r200_dri.so is available, then it says:
   OpenGL renderer string: Mesa DRI R200 (RV280 5960)  TCL DRI2
