Before deciding whether to merge or not in trunk, I would really like to see an alternative Qt based solution, not involving win32 API. I just played a bit with the QImage/QPixmap idea, and it works more or less, although it's a bit slow. See the attached 10 lines patch.


Attached is an alternative that is much closer to working.  The two main issues are:

Good! That should even be faster, by bypassing the QPainter stuff.
1/ star labels only show correctly when a cluster/nebula is selected (need the pulsing selection box)
 - planet labels, grid labels, etc., are fine
 - star labels are actually there, but they're black boxes

try to glEnable(GL_BLEND)
I had expected it was already set (which, upon checking, it is), so hadn't bothered with it.  Added it anyway - makes no difference.  I've also noticed that the star labels disappear when constellation art is on, but the planet labels are still okay.  What's different between planet and star labels? (I'm guessing there must be some GL state different? But what?)

2/ text is not rotated (grid labels for example)
 - is this a limitation of bitmap images?

glDrawPixel doesn't use the matrix. Try to draw the texture using a real gl call.
As an infamous politician here once said, "Please explain!"

Thanks a lot! If you make taht working you'll be a hero for ATI users ;)

I've been delaying purchase of a new laptop because the one I want only comes with ATI.  Hadn't really thought that Stellarium may not work, but I need a replacement soon - need to get this bug fixed!

I'll look at it again in the morning.
