Hello all, 

This is very likely a simple fix:

When loading textures and superimposing them atop other stimuli, I often get
visual artifacts around the edges of the texture, likely due to OpenGL
texture manipulations. I have included a jpeg image of a screen capture
with one such texture artifact (in this case, the top and right edges are
shown as grey bars, where the texture meets the background).


I had a problem with this too. I was using transparency in .png files but not loading the texture data as gl.GL_RGBA. As soon as I changed the texture format it all went away.
