glInvalidateFramebuffer problem

Esenthel

Hello,

My app works OK on:

-Windows Desktop GL

-Apple iOS iPad mini 2

-Samsung Galaxy Note 4 (ARM Mali-T760)

-Sony Xperia XZ2 Adreno 630

However when running on:

Huawei Mate 20 X (ARM Mali-G76) version OpenGL ES 3.2 v1.r16p0-01rel0.95d2435cbe2284d49b9bbcf5b1624fdd

Then I'm getting problems.

Expected results:

ARM Mali results:

after touching the screen to rotate the camera

I'm suspecting a driver bug.

This problem appears to be related to 'glInvalidateFramebuffer', if I replace all glInvalidateFramebuffer calls with glClear (or just remove the glInvalidateFramebuffer calls), then it starts to work ok.

Please check this link which includes APK files and images:

Thank you,

Greg
