Calling glGetError without a context is invalid, as it is a gl function and you should have the context before calling it. And have you tried calling glFinish() or glFlush() after the operations?
I'm also wondering what you mean by "submitting the results to GPU", if you never read back the texture data to CPU won't you just keep working on the same data? The piece of code you commented as submitting the results just binds another texture.
