[Solved] color depth for displaying images

[Thomas Schäffler <mailing ratzebaer de>]

Hi,

I looked at my display settings and found that only 16bit was set as color 
depth. I switched to 24bit and now it looks the same in all apps.

Sorry for the asking first and looking afterwards. It is interesting though 
that qt and gtk-apps behave that differently. I have switched to gnome before 
and used the standard SuSE theme without any changes.

Thanks for helping

Thomas
