Description martin 2009-03-17 04:41:45 UTC

repro steps using git head + G45:

1. enable UXA (it won't repro with EXA)
2. enable compiz
3. open firefox, maximize it with about:blank (any program that makes the screen mostly white will do it)
4. open gedit, maximize it and open Edit::Preferences::Fonts&Colors and select "Oblivion" color theme (any application with a large dark or black area will do it).
5. now single click the gnome taskbar entry for gedit slowly and repeatedly to minimize and maximize gedit multiple times


Expected:
gedit should be animated normally by the compiz default minimize/maximize animation

Actual:
gedit is animated by the compiz default minimize/maximize animation however, all dark areas becomes translucent _during_ the minimize/maximize animation. black areas becomes 100% transparent during the animation.

Comment 8 martin 2009-03-17 05:18:09 UTC

I use a dark theme in ubuntu (the dust theme) which makes this bug very annoying / prevalent.

Comment 9 martin 2009-03-20 08:03:22 UTC

I installed upstream kernel 2.6.29-rc8 now, and then the bug doesn't repro anymore.

Eric, if you can guess which commit fixed this issue, then please to give me your guesses and I can try and possibly cherry pick them for ubuntu Jaunty. Thanks.

Comment 10 martin 2009-03-20 08:17:59 UTC

I still see rendering defects with the 2.6.39-rc8 + recent userspace config though.

When doing this:
0. (with compiz running under UXA)
1. start a gnome-terminal with "white text on black background" theme and run "ls -al" to fill it with some white text.
2. do "gedit *.txt" on some files and use color theme "oblivion" (dark background).
3. repeatedly press the gedit taskbar entry to minimize/maximize gedit triggering the minimize/maximize animation in compiz. the white test from the gnome-terminal in the background cuts very clearly (opaque not blended at all) into the gedit window as it's gliding into maximized state. It's not until the maximize animation is completely finished that the opaque white text from the gnome-terminal in the background disappears.

It's strange because before it was the dark background of gedit that incorrectly got transparent and now instead the white text from a background windows burns though in an opaque way making the animation look bad.

Comment 11 Eric Anholt 2009-03-20 11:36:33 UTC

Could you retest with Mesa master?  I'm getting exactly the expected behavior now.

Comment 12 martin 2009-03-20 12:19:39 UTC

mesa master works perfectly for me as well. You rock Eric!! Thanks a million..

Comment 13 martin 2009-04-09 02:18:51 UTC

If some distro maintainer is looking for the commit that fixed this bug for cherry picking. Please have a look at this one:
