After some more testing, it seems to come from the Ubuntu Theme "Ambiance". If I choose another theme, like "Radiance", the contrast is ok and menus are readable.
I tested the same sweethome3d version on Ubuntu Lucid 10.04.4 : the contrast is ok for both themes Ambiance and Radiance. So this seems to be specific to Precise (and maybe Maverick/Natty/Oneiric : I did not test) ** Attachment added: "Screenshot of sweethome3d menus with Radiance theme" https://bugs.launchpad.net/ubuntu/+source/sweethome3d/+bug/946500/+attachment/2879640/+files/SweetHome3D%20menus%20with%20Radiance%20theme.png ** Also affects: light-themes (Ubuntu) Importance: Undecided Status: New ** Summary changed: - Menu color make them unreadable + Menu color make them unreadable with Ambiance theme in SweetHome3D -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/946500 Title: Menu color make them unreadable with Ambiance theme in SweetHome3D To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/light-themes/+bug/946500/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
