11:51 PM Revision 1f19fba8 (library): Port the Mali flash fix to the OIT branch.
Leszek Koltunski
01:31 PM Revision 6672d895 (library): I am pretty sure this time the flashing issues on Mali T880 r12 driver are finally fixed.
The fix: a queue of FBOs render to, just like before, but this time in DistortedScreen we blit not the current FBO, b... Leszek Koltunski
01:30 PM Revision 586b5fa1 (library): Port another commit from master.
I spoke too soon, the ARM Mali flashing is of course not fixed yet. The previous commit fixed Triblur, but the bug is... Leszek Koltunski
01:16 PM Revision 8ebbc730 (library): Port a commit from the master branch.
Finally properly fix the flashing on ARM Mali T880 GPU.
The flashing is caused by a 'full pipeline flush' (see DarkP...

11:17 AM Feature #32 (Closed): Make it possible to use multiple copies of the library
Currently, probably due to various static variables all over the place, if an app initialises too OpenGL contexts and... Distorted Admin

12:07 AM Revision baa3989b (library): Revert last changes to the postprocessing FBO.
This reverts commit 2dbed690bdbee80d9bfb22c800073855eb5d0946. Leszek Koltunski
11:18 PM Revision f4d6114c (library): I spoke too soon, the ARM Mali flashing is of course not fixed yet. The previous commit fixed Triblur, but the bug is still reproducible elsewhere (only in the 'postprocessed' apps though).
This commit introduces a circular queue in case of the postprocessing FBOs - with little success though. Leszek Koltunski

11:09 PM Revision 01b9a241 (library): Minor.

10:08 PM Revision b81d5d40 (examples): Stencil App: Do not request any special EGL config; with DistortedScreen now buffered, we don't have to (and in fact this config doesn't exist on HTC Desire 12)

09:33 PM Revision 3f70dd29 (examples): Try and avoid re-sorting the children by buckets (if we can!). This makes change in rendering order in the 'Transparency' app actually work.

02:03 PM Revision 1440748a (examples): In an attempt to contain the flashes on Mali GPU, re-structure the post-processing FBOs from 1 FBO with 2 color attachments + combined depth-stencil to 2 separate FBOs sharing a depth-stencil texture.
Result: this appears to make the flashes slightly worse. Leszek Koltunski
