Help
An ugly white border appears around the web player when using the GLSL renderer. This varies based on the current scaling shader, but nearest/greyscale, epx, and hqscale seem to be the only shaders that mostly avoid it. This might be due to poor precision in the fragment shader or by the default white fill of the framebuffer texture bleeding into the image. Either way it would be nice to get rid of this.
Potentially relevant pull request.

Updating status to: Fixed
Issue fixed in: 2.92f
Fixed in GIT dea0d06e. There were a few ways this could have been fixed but I felt like the cleanest was to just add a glClear for the framebuffer object in glsl_sync_screen. Other platforms were avoiding this bug due to the glClear after gl_swap_buffers that was only disabled for Emscripten builds.
