somehow, compiz works on my main user,
but i can't replicated it in a new user.

when it fails, it leaves the windows border less and unmovable
sometimes it gets a bit more messed up with the position that
the mouse can click displaced from the real position of the mouse
by quite a large distance.

At first it didn't work in my main user either, but
at some point i noticed that it worked....
I'm not sure what i did, and can't narrow down the fix.
I tried copying over .trinity, .kde, .config, .cache, .local
various config .files from my home, but still doesn't work....
compiz --debug seams fine....

I'm using the default compiz install of linux mint 18.2
compiz works fine in mate for all users
compiz works only for my main user under trinity

the compiz-trinity packages seam totally broken.

any ideas?
