I modified the latest svn version to fix this problem for other themes than Ambiance. Transparency doesn't work, but now you can change the background to whatever color you want. The file is in attachment.
Save the file to your home folder, copy it to /usr/bin (sudo cp checkgmail /usr/bin) and make it executable (sudo chmod +x /usr/bin/checkgmail). Restart checkgmail, set the tray background, and restart again. ** Attachment added: "checkgmail" https://bugs.launchpad.net/ubuntu/+source/checkgmail/+bug/236046/+attachment/1521578/+files/checkgmail -- checkgmail tray background colour cannot be changed https://bugs.launchpad.net/bugs/236046 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
