[Wine] Re: state of OpenGL in software rendering

[Aerilius]

The problem is, SketchUp has a feature to export 2d images of a 3d scene in various file formats (jpg, tiff, png). In Wine, it exports without crashing, but the images are black or transparent, that means they do not contain anything visible from the 3d scene. The developers of SketchUp say this feature uses "software rendering".

My graphics card is an Intel mobile 945 chipset (laptop) and an ATI HD5450 (desktop, proprietary driver, at least version 11.1). I'm top contributor in the SketchUp Help Forum and nobody else has it working (on different graphics cards, including Nvidia).

We tried to find something in the log when starting SketchUp from the terminal, but there there are always different unreproducible error messages that seem to be not related (rasapi32).
Just now I tried a debug log with 
WINEDEBUG=+wgl wine sketchup &> log
(found that command when browsing bugzilla, I attached the log to the bug report.)
