Comment 5 for bug 1758009

I resolved the problem for myself.

I searched for compiz related files in my wife's home directory and found .config/compiz-1/compizconfig/config

In there, she had a config resembling the following:

[general_ubuntu]
profile = unity-lowgfx

I, on the other hand, had a config like this:

[general_ubuntu]
profile = unity

I changed her config to match mine and logged her back in and it was fixed.

I note others complaining of similar errors found that switching *to* low GFX fixed the errors for them prior to a patch hitting upstream.

I don't know how my wife got the lowgfx config while I didn't. Neither of us have manually messed with these configs in the past. Both our systems were working fine yesterday (23 March UTC+8).
