NVIDIA: Unity does not refresh windows often enough

[Pendrokar]

When selecting a game object, the inspector might not refresh at the right time, showing the previous game object. Same thing may happen when writing text in a text input and seeing the previous state.

Steps to reproduce:

• Click on a GameObject.
• In inspector click on show/hide Transform tag multiple times until the line is turns up gray as if it is opened, but doesn't seem like it.
• When this happens, click the inspector tab(to refresh the window) and then on a parameter. When writing you should see only the previous state of the text.

Reported on:

• Ubuntu 13.10/14.04
• Wine 1.7.15/.16/.17/.18
• Graphics card: NVIDIA Geforce 9600GT/GT320M
• NVIDIA driver (proprietary) 319/331.38
• NVIDIA driver (open-source) 331.67/334.21/337.12/337.25 (These are made available when adding ppa:xorg-edgers/ppa repository)

Most likely culprit:

NVIDIA graphics drivers, although in -force-opengl mode other vendor graphics cards also experience this bug.

Workarounds / How to solve:

• In NVIDIA Control Panel(nvidia-settings), in Powermizer set Preferred Mode to Max Performance.

Or

• Enable "Strict Draw Ordering". You have to add a key to the registry, see UsefulRegistryKeys. For PlayOnLinux installation of Unity, there is an option in its configuration. This might impact performance.

Or

• Use the Nouveau graphics driver, which does not have up to date 3D acceleration.
