Found a solution, which is crappiest but... use the horrible Unity switcher, I was using Compiz Ring switcher, changed back to Unity and now the problem doesn't occur. I needed something with a app preview but I guess I'll have to conform to the Unity stuff.
As a palliative I created a launcher on the dock for Scale, so I can click and see all windows, check if the processes I'm running are over yet or not, and then keep working. Not the best, but endurable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/729979 Title: [nvidia] Windows appear blank white To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/729979/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
