Revision 073e5a7a

Added by Leszek Koltunski almost 4 years ago

Another attempt at fixing tthings on early Qualcomm OpenGL ES 3.0 drivers.

The previous version does not work on Adreno 405 driver V@100, present for example in a Asus ZenPad 8.
Revert the packed 'ivec2' UBO in the vertex shader back to a 'std140' ivec4. This comes at a price if bumping into the bug on Qualcomm driver version 331 on Adreno 308 - i.e. Samsung Galaxy J4+ again.

On this platform, switch off Gigaminx and then set MAX_COMPONENTS to 98.
