Turn compositing ON or OFF at Control Center > Windows and see what happens.
Also, you can install MATE Tweak and select window managers there (with/without compositing..
Thanks for your reply TonyT
Yeah I did all that, I ended up installing some packages and eventually got it working with marco hw compositor,(not sure witch package got it working) then I installed compiz fusion but I ended up with the same issue. So I gave up and installed jessie.
everything is working as it should and I got compiz-fusion installed
I will give it another go when Debian 9 has been released
Thanks again Tony
