Composite extension failure


Description Dmitry Zamaruev 2007-01-23 10:18:45 CET
When using terminal with real transparency it refreshes sometimes foreground with transparency.
For exmaple when editing file with vim, moving cursor around will cause some area refreshed with background and foreground. 
When just typing - it will make background transparent, but foreground normal. When refreshing - it will refresh foregroud with backround to transparent state.

Here you can view transparent foreground bug, on 'else','for' statements, or background fire on text.

That's either a bug in the compositor or in VTE.

Looks a bug with Xorg or Render. ARGB32 in depth 24 cause such problems, try switching to 16bpp depth, ie change:

        DefaultDepth    24


        DefaultDepth    16

in the screen section of xorg.conf.

Switching to 16bpp resolved problem and I could use this as temporary workaround.
But is this bug in xfce package, or I shoud post this bug to Xorg team?
Comment 5 Olivier Fourdan editbugs 2007-01-24 12:25:48 CET
I think it's a bug in Xorg or in Xrender, because xfwm4 just use that for rendering. Also, Switching to nVidia proprietary driver fixes the issue for all depth, which makes me think that the problem is in Xorg.
Comment 6 Olivier Fourdan editbugs 2007-06-24 09:46:07 CEST
As stated, I think this is a problem with the Xorg drivers;
