Ticket #308 (closed usability: fixed)
No more 16bit accumulation buffer visuals available

Using 2.4.0 glxinfo (and our own application) is not able to access visuals with 16bit accumulation buffers, only 8bit buffers are available which are useless for accumulation purposes with 8bit color buffers.
Searching in the source tree revealed that this might have been caused by a change in hw/xquartz/GL/capabilities.c on 11/6/2008, when access to all buffers with more than 8bit was disabled. I think this is correct todo for color buffers but not for accumulation buffers.
Can the function handleColorAndAccumulation() be split in two. One for color buffers and one for Accumulation buffers so that the 16bit accumulation buffers can be accessed and hence OpenGL applications which rely on the accumulation buffer work again?
- Priority changed from critical to major
- Status changed from new to assigned
- Milestone set to 2.4.1
