In a VNC session to a remote computer that was using a Windows XP system and another VNC server to whom I was able to connect fine before upgrading to the Kubuntu 3.51 ppa version. Now when I connect the screen switches the remote red and blue, so red looks blue and yellow looks cyan and blue looks red. The green is normal. I was using the scaling feature. I did not try it without the scaling feature. The XP taskbar and title bars all came up as a bright orange.

Reproducible: Didn't try
