Bug#1081962: libgtk-4-1: complains to terminal on Intel graphics cards

[brian m. carlson]

Package: libgtk-4-1
Version: 4.16.1+ds-2
Severity: normal

I use NeovimGtk, which is a GTK+4 graphical frontend to Neovim.  With
the new version uploaded to unstable today, spawning an editor includes
the following messages on the terminal:

  MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:763: FINISHME: support YUV colorspace with DRM format modifiers
  MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:794: FINISHME: support more multi-planar formats with DRM modifiers

Since I realize NeovimGtk is not in Debian at the moment, this can also
be reproduced with gnome-text-editor, which is:

  % gnome-text-editor foo.rs
  MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:763: FINISHME: support YUV colorspace with DRM format modifiers
  MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:794: FINISHME: support more multi-planar formats with DRM modifiers

It is also reproducible with gnome-mahjongg, so I assume it happens with
all GTK+4 apps.

GTK and the libraries it depends on should never write to stderr unless
a user-visible problem has occurred, since this is annoying when being
invoked in the terminal.  Since the software appears to be otherwise
functional here, it should remain silent.

I realize this may be a bug in Mesa, but if it will not be fixed
promptly, please apply a workaround to revert the appropriate parts to
the 4.14 version in the meantime.
