     GNOME version: ---

I found gleffects has performance downgrade issue on imx6Q soc. Check the code
found that gleffects will allocate 5 middle textures. When 1.8.1, these five
textures are not PBO texture. But 1.10.0 will get dafault glmemory allocator
which will be PBO glmemory allocator for GLES3.0. PBO glmemory is not necessary
here.
