Bugzilla Bug 150492

The problem only appears, if there is the following line
 Option "Composite" "Enable"
in file /etc/X11/xorg.conf.
At first any djvu file is shown properly, but some gui elements such as menus
and the icon in the upper left corner have incorrect colours. Also I can scroll
any page down.

However, trying to scroll a page up damages the image.

After that only the part of the page out of the current visible domain can be
correctly shown by scrolling down.

New request for the page restores the proper image.
This problem appears with all stable djvu version up to 3.5.17.
ddjvu works properly, so I think that it's a gui only problem.

Some additional information.
1. When I open menus in the djview window, I get some messages like these:
QT Warning: X Error: BadMatch (invalid parameter attributes) 8
  Major opcode:  62
  Minor opcode:  0
  Resource id:  0x2800043

2. There is a workaround for the problem.
$ XLIB_SKIP_ARGB_VISUALS=1 djview
works properly with "Composite" enabled.

This bug is very similar to:
http://sourceforge.net/forum/forum.php?thread_id=1607327&forum_id=103285)
And it was reported that this is fixed in currently not in the tree
djvu-3.5.19. I'll commit it ASAP. :)

This should be fixed in 3.5.19 which is now in portage. Please, test and reopen
if the problem persist.
