use fbo to shift texture one pixel to the left per second The attached file is a hacked up version of the textured cube demo from learningwebgl.com. I was experimenting with framebuffer objects to create the "ping pong", render to texture technique that is useful for gpgpu stuff. When loaded, you should see a canvas filled with a texture that then shifts to the left, one pixel every second. It works perfectly using the nightly builds up to revision

breaks. I see a rendered texture, but there is no shifting to the left. I am completely new to OpenGL so it is quite possible I screwed something up, but I thought I would file a bug since I was able to get it working for certain builds and not others.

I've resolved my problem and this bug can probably be ignored. Turns out I was using the wrong width and height in my call to renderbufferStorage(). For some reason this doesn't matter before revision
r51062
, but does afterwards. Anyway, everything works now, carry on.
