I think this is due to the switcher buttons. I am using 10.10/Maverick on Acer AspireOne and found this workaround -
Click on View -> Switcher Appearance. Disable "Show Buttons". The window will stop jumping :) You can use the Alt-V, S, B, B <Enter> combination if your window is already jumping and you don't feel like restarting Evolution. -- Evolution netbook resizing goes wrong https://bugs.launchpad.net/bugs/488244 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
