Bug 364

---- Reported by qwerty999 2008-09-26 13:36:26 ----

OS X release 10.5.5 causes all text rendered via the TextRenderer to become garbled. This has been 
reported on both the JOGL forums and the Apple Developer forums with no response. It is unclear what is 
causing this problem and whether or not it is confined to particular video cards, etc.

Btw, neither of the following have helped (which were suggestions from other bugs with TextRenderer 
issues):

setUseVertexArrays(false);
recompiling and forcing usingVBOs = false;

Bug occurs with every font I've tried at every size. It occurs on *every* program I've tried that uses 
TextRenderer.

Sorry, I haven't been keeping up on the forums. Thanks for the report.

This is a hardware-specific bug; it doesn't happen on 10.5.5 with Intel Integrated Graphics hardware, 
but does with NVidia hardware.

It appears that glTexSubImag2D calls are broken pretty badly -- as far as we can tell they are using the 
previous call's data for subsequent calls. The workaround is to change the markDirty() calls in the 
TextRenderer to zap the entire backing store instead of just the rectangle corresponding to the current 
glyph.

Needless to say, we do not want to put such a hack workaround into JOGL. We are working with Apple to  
get confirmation, diagnosis and resolution of this bug.

A thread was started on the apple developer forums as well by other frustrated 10.5.5 users:
