EXT_color_buffer_float question #422

Closed Sisah2 closed 1 year ago

Sisah2 commented 1 year ago

Just asking when initializing, gl4es say that EXT_color_buffer_float is supported and used, yet based on documentation it require opengl es 3.0, so how is it? What happenning here is invalid framebuffer operation, but half_float seems to work.

May it be driver bug? Where it expose es3 extension even thought its on 2.1 context? Also if not supported (i expect always? As it need es3?) does gl4es automatically try to use half_float when supported?

Hmm, maybe its just something broken with GL_OES_texture_float on my side, i close this.
