Default minimize animation (zoom) not working properly with proprietary nvidia drivers

[KillerCookie]

What steps will reproduce the problem?

1. Install any currently available proprietary nvidia driver
2. Minimize a windows

What is the expected output?

- the default window minimize effect "zoom" shrinks the whole window into the launcher

What do you see instead?

- during the animation the window content is hidden, just the decoration is shown

Status changed to 'Confirmed' because the bug affects multiple users.

[ovdeathiam (ovdeathiam)]

Also resuming a window if it is still minimizing results in a window with decoration but without content (black).

If the minimize animation finnishes however then resuming the window resumes the content.

[ovdeathiam (ovdeathiam)]

Something I found out just now: If you get the black content window and again press minimize, then the window content during minimize animation is correct. It is as if the minimize animation toggles the window content on/off.

[George Giannoulis (georgegiannoulis83)]

I think the bug its in Compiz/Unity and not nvidia. Open compiz config settings manager and go to the Unity plugin -> Switcher and uncheck "Show minimized windows in switcher".

[ovdeathiam (ovdeathiam)]

Yes, this does fix it.

The switcher (afaik its the alt+tab functionality) is still shows the minimized windows in switcher even when it is unchecked.

It is the unity plugin bug most probably.

[KillerCookie (mk3ll3r)]

I was unable to spot the mentioned setting "Show minimized windows in switcher" in CCSM / Unity Plugin but i found out that disabling the Setting "Show live previews of windows in the Switcher" at the same place solves the bug. Maybe it its the same setting but got renamed?

I dont know but now the animation is working - somebody should have a look at the code of the mentioned setting.

[KillerCookie (mk3ll3r)]

it seems like disabling "Show live previews of windows in the Switcher" has some unfortunate side effects. The "Show Desktop" button is not working properly - it hides the windows at first click but it does not restore them on the second.

[Damien (humanisfood)]

i am having this same issue in 13.04.

[Leonardo Herman (tentaculo)]

Disabling "Show live previews of windows on the Switcher" fixes it on 13.04

[Shaun P (sigmagammapi)]

The above also works on 14.04 / Trusty which is in development.
