Bug#610294: qt4-demos: visibly ugly dithering under vnc4server (not with clean $HOME)
Package: qt4-demos
Version: 4:4.6.3-4
Severity: normal
Steps to reproduce:
1) sudo apt-get install vnc4server xvnc4viewer
2) vnc4server -depth 24 -geometry 1024x768 :7
# and enter any password you like
3) DISPLAY=:7 qtdemo &
4) xvnc4viewer -passwd ~/.vnc/passwd localhost:7
5) choose Animation Framework/Easing Curves/Launch
6) (cleanup) vnc4server -kill :7
Expected results:
2)
You will require a password to access your desktops.
Password:
Verify:
xauth: creating new authority file /home/testi1/.Xauthority
New 'lindi1:7 (testi1)' desktop is lindi1:7
3)
QGLTempContext: No GL capable X visuals available.
Unrecognised OpenGL version
5) no visible dithering is done
Actual results:
5) very visible and ugly dithering is done
More info:
1) This bug does not occur with a clean $HOME. With strace I narrowed
it down. Just adding
[Qt]
4.6\libraryPath=/usr/lib/kde4/plugins
to ~/.config/Trolltech.conf makes the bug occur. I have no idea what
wrote it there. I think there are basically three different options
here:
1.1) it was written by some older version of some package. In this
case it makes upgrading difficult and we might want to ask users to
remove their .config/Trolltech.conf after a major upgrade, right?
1.2) it was written by an application that still is in debian
(squeeze). In this case we should try to find out which application it
is and fix it.
1.3) it was written by some application that is not in debian. In this
case the bug should probably be closed.
