Some mesa examples are being rendered upside down.

Solution Unverified - Updated -


  • When running some of the Mesa examples, we found that some examples are being rendered upside down:

    1. readpix : press f, and notice the text / images being drawn upside down
    2. tessdemo : Clicking on the mouse places a point on the correct X coordinate, but on the opposite Y coordinate
    3. winpos : running the example, the images are upside down.
  • The National Instruments LabView 2013 cannot at present be used on RedHat Enterprise Linux 6 due to mesa-libGL Bug 66213 - Certain Mesa Demos Rendering Inverted (vertically). This causes the 3D Math Plots to be drawn inverted when drawn as part of the LabVIEW front panel.
