I have recently upgraded from 17.04 to 17.10.
Upon upgrading, I noticed the "wobbly windows" feature wasn't working anymore.
I opened the CompizConfig settings manager and the feature was active.
I tried to disable and re-enable with no effect.
I am not knowledgeable enough to figure out whether any of the detailed settings might be the problem - here is a screenshot of what my settings for wobbly windows look like:
Note: I have tried disabling all other effects, with no change.
