I found a workaround for me! I log out, then choose my login and down below I select "Classic (No effects)" and now all windows seem to work with no blank screens.
5 or six firefox windows are ok. and resizing the text editors is working. I will still appreciate any advice, but I will be fine to operate like this for now. I don't like the Ubuntu login tool bar on the left anyway. Why can we move that think to the bottom like every other window manager? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/752445 Title: Intermittent white window contents when maximizing/switching windows -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
