Since I can't reproduce the bug, I have created a branch with a bit more logging output:
Could you please test again for us?
Unless you can compile yourself, just wait for a few days for the PPA to be updated. I'm interested in seeing the
Graphics: OpenGL: ShadingLanguage: line; if the parsed double is the same as the version string, and if not, what it looks like.
ETA: The added log output has hit trunk now and I've triggered a new PPA build, which should be ready in a few hours.
