Hello,
i have very strange experience on those 3 phones. All of those should have Power SGX 540 chip but i’ve got different results compiling shaders.
Samsung S9100 - android 2.3.6 - compile ok
Samsung Galaxy S - android 4.2.1 - compile failed without reason
Samsung S9000 - android ? - compile crash
I also tested this shader in 4 shader compilers - SGX 535, 540, 543, 6xx and all went fine.
I also tested it in windows emulator - all goes fine
So, it seems to me like shader version problem, so can you, please, help me, what to do with it ?
If it compiles, everything goes fine - no artefacts seen
Best regards and thanks
Petr Sovis
