Are there any known bugs with glCopyPixels() on ATI Radeon 9700? There
is an issue affecting only my users with PowerBook G4 1.5 GHz 17"
models... glCopyPixels is taking an average of 65881 microseconds to
complete. On all other hardware the average is 15-30 microseconds.
I use aux buffer #0 to cache my static background, and blit to the
front buffer (or back buffer, if double-buffered, which it's not) each
frame before dynamic drawing. glWindowPos is {0,0}. glBlend is
disabled. No glScissor. Identity matrices... basically all default
context settings. The last VAO and texture are still bound, but VAR is
disabled...
