[pkg-cinnamon] Bug#785336: Further info

[Amie Amaman]

I've got some further info on the bug:
Graphical login for a different user (root) works just fine. Also, logging in with that "software rendering" (or something) option (seems to be a failsave option) aviods the bug, however, moving windows around lags a lot then, so it's no permanent workaround.
I also realized that the terminal window I am able to bring up via desktop context menue (like explained earlier) doesn't have window title bar nor window borders. Only after the command "cinnamon" or "cinnamon-launcher" they appear. So it seems to have to do with cinnamon's window manager. The fact that graphical login for root works well indicates that installing software (updates + eclipse) was not the problem. Remains the opacify windows extension which might have caused the bug. I'm no expert, but opacifying windows seems to have to do with the window manager. It also suites the fact that grapical login with the "software rendering" option works. What do you think?
However, I've disabled the extension and the problem persists.
