I am also affected by this bug and it is especially annoying when using eclipse IDE, which "collapses" to a tiny barely visible line (see attachment). This bug is besides ubuntu 14.04.x also present in 14.10 and 15.04! I asked about this beaviour in ubuntu ask (https://askubuntu.com/questions/569574/ubuntu-eclipse-window-disappears) and there is one more person affected by this bug
