Chromium sometimes prints the following error message: "GL ERROR :GL_INVALID_OPERATION : glDrawElements: attempt to render with no buffer attached to enabled attribute 2" This happens in the following situation: 1) There are two FECustomFilters on the page. 2) One FECustomFilter has a detached mesh. One FECustomFilter has an attached mesh. The detached FECustomFilter has one more vertex attribute (a_triangleCoord) than the attached FECustomFilter. 3) The detached FECustomFilter is destroyed, but a_triangleCoord remains bound. 4) The attached FECustomFilter tries to render, but Chromium notices that there is no buffer attached to the a_triangleCoord attribute. We should unbind the vertex attributes after a custom filter is applied.

You can put cq+ yourself in this case (no changes needed from r+). I'll do it now.
