Thanks [~aghaisas] for sharing new 3D Box difference. I think this also might be specific to x86 as i see red tinge in both Metal and OpenGL for 3D Box in M1. Attached image for reference.

This is still reproducible in the latest test run. Another observation is for "3D Box" demo that could be related - In ES2 the top and right side of the Box although appears black has a red tinge - RGB=(46,0,0) In metal, these two faces appear Black with RGB=(0,0,0) It might be an oversight in earlier testing due to the shadow appearing almost black.

Made changes to not pass bool variable(Because this is reproducible only in x86 and padding can be an issue) in fragment shaders uniforms and use float4 vector only to pass all texture map related flags and shared the patch with Ambarish. Even with this patch issue is seen.

This is not reproducible in M1 aarch64 Macbook Pro which is have. This is reproducible only on x64 machines. Also [~arapte] helped me to identify that this issue is happening after JDK-8310658 change.
