--- Comment #21 from m00nraker <m00nra...@gmx.net> --- Thx for reply and working on that bug-report.

To make sure that everything is ok, could you maybe upload a complete diff-file for me to apply? (I'm confused about the "...GlxBackend::initRenderingContext() return false;" in your debug output code in comment #14). Do not forget that I'm not a software developer and I haven't many experience in editing source code. So a complete diff file would be the better choice for me, to make clear, that everything is as it should be :-) Nevertheless I'm quite sure, that I did it right. -- You are receiving this mail because: You are watching all bug changes.
