ARM Mali devices wrongly report that OES_texture_float is supported

Han Han

Actually Mali GPU does not support OES_texture_float. For example, you can not open this webgl websitehttp://madebyevan.com/webgl-water/

How we resolve this issue?

    None of the Mali drivers expose this extension string so this sounds like an issue with the browser WebGL implementation you are using rather than the Mali drivers themselves.

    Note that the Mali GPUs which support OpenGL ES 3.0 do support floating point textures for OpenGL ES 3.0 contexts, as they are a mandatory part of the OpenGL ES 3.0 API and no extension is required.

    The r8p0 drivers for the Mali-T760 and T800 series hardware also support the GL_EXT_color_buffer_half_float and GL_EXT_color_buffer_float extensions for floating point render targets.
