Description Andrea Cimitan 2007-09-16 18:45:11 UTC

I got this bugs for _months_... And I'm not alone.
The metacity titlebar gets corruption on maximized state AND use_metacity_theme.

The strange thing is that today I've set the metacity_theme_opacity in /apps/gwd (gconf) to 0.9 and the curruptions disappears to nearly 98% (I've just an hint of cottuption on the top-left... but not completely corrupted as in the screenshot).
So it seems a problem in the metacity rendering part, which is completely visible (80% of corruption) when using opacity = 1 for active and inactive windows.

Other guys... (probably all of us have this problem as I don't know anyone without it)

this is the piece of code that causes the bug:

This makes me wonder whether this is similar to another gwd bug--

Does adding the --sync parameter to gtk-window-decorator fix the problem?

Comment 6 Andrea Cimitan 2007-10-23 05:38:30 UTC

yes this fixes.
but why we should add the synchronisation? Maybe the --sync could slowdown the performance on low systems.
I guess it's better to fix the leak

Comment 7 Andrea Cimitan 2007-10-23 07:07:59 UTC

the titlebar is rendered better but now buttons sometimes are not updated and appear slways in *pressed* state. (using --sync)

This was an issue with older versions of the Nvidia drivers, which is fixed in the 180.xx series.
