>Description:

I switched from XFree to in-tree xorg recently and installed all pkgs from
scratch.

One of the pkgs is qvwm-1.1.12nb8, and it has severe display problems - it
doesn't show any content from .ani, .xpm, .png or .jpg files (didn't try
others).

It is using imlib-1.9.15nb4 to display images, so other users of this lib
might be affected too.

Here is a screenshot:

  http://www.netbsd.org/~martin/qvwm-display-bogus.png

Note that apparently the alpha channel works, but the colour planes are not
filled (seem to be random leftovers). The logo, especially the flag shows this.
The buttons on the xclock frame are also empty (I guess the borders are drawn
by code, the content, from a png file, is missing).

I see this on both an amd64 machine with Radeon driver, as well as a sparc64
one with ffb driver.

I'm filing this as xsrc and not pkg because the pkg has not changed. Maybe
it is an application (or imagelib) bug, but if so XFree did cope.

>How-To-Repeat:
Install the wm/qvwm pkg and run it in default installation. Note the missing
frame window button contents and desktop icons (it is obvious even if you 
never ran this wm before, and the pkg is pretty lightweight).

>Fix:
n/a

 Forgot to mention: other apps can display arbitrary images just fine (I tested
 firefox 2 for example). So there must be something special going on due to the
 way imglib or qvwm display the images.

 After updating to -current again (I guess Quentin's recent fix is the key)
 *plus* disabling the Composite extension in xorg.conf this works again.

 I have no clue what "Composite" even is and how it would interfere with
 blitting. Since it seems to be buggy, should we disable it by default?

 I filed an upstream bug report for this:

   https://bugs.freedesktop.org/show_bug.cgi?id=18999

 My vote is still on disabling Composite by default.

 Hi,

 it turns out that nedit is also affected by the problem and fixed by 
 disabling the composite extension. With the extension enabled the whole 
 window is full of garbage with only a few recognizeable parts of the normal 
 window content.

 It's interesting that other motif programs such as xpdf and vim-motif aren't 
 affected by the issue.

 The only remaining program with problems I know of is audacity. The window 
 content is basically Ok, but the waveform display is broken. This wasn't 
 fixed by disabling the composite extension.

 I'm using X.org from NetBSD 5.0_STABLE here.

I fixed some problems today with Composite and DAMAGE support, can you update your sources and try again?

This is a plain pkg bug in Imglib, not related to in-tree xorg
