Fade Windows can get stuck if rapidly toggled

[Nick Lawson]

Binary package hint: compiz-fusion-plugins-main

Tested on: Fresh install of 10.04
Note that I'm assuming that 'fade windows' comes from the main plugins package - it did not seem to be in either? Maybe its part of the core?

The "Fade Windows" plugin is used by several other plugins (such as the ADD helper). If one of those plugins causes it to rapidly fade and unfade, it can get stuck faded. This only happens when in "constant time' mode - constant speed never sticks.

To cause this problem:
* Enable Fade Windows
* Switch Fade Windows to "Constant Time" instead of "Constant Speed".
* Cause windows to rapidly fade and unfade (the goal is to have a fade overlap an unfade on the same window).

My favorite way to reproduce this is to turn on another plugin like ADD helper (Which makes unfocused windows fade) and then turn on Ubuntu's "Select Windows When the mouse moves over them" option (in system->preferences->windows). Then just put two windows on your desktop and shake the mouse rapidly between them to cause them to flicker. Note that you HAVE to have 'constant time' not 'constant speed' selected.

There's probably an easier way to reproduce this, by turning the fade time very high so you have plenty of time to cause multiple fades to begin on the same window or something.

Note that even without trying to cause this to happen, after about a day of using the machine, all windows will inevitably have had the fade effect stick just due to alt/tab or popup windows or such... so the only workaround is to make sure its set to "constant speed".
