Quad and grid doesn't work (latest alpha28)

quads and grids with any shader won’t display in ex9 renderer completely randomly (and it never works if i use MRE). connected box to the same shader it worked. and this is a quite huge bug

bois please!
provide a sample patch with such stories!

ok now i opened vvvv and tried to reproduce the bug but now everything is fine. when i noticed this i restarted vvvv several times and neither of the restarts were working. wierd. anyway here’s the patch if this bug is present both of the renderers should be blank black. (2.1 MB)
