Comment 40 for bug 763148

I guess this bug seems to be fixed for most folks post-raring and late changes restricted to Precise. However, even in Trusty &0.9.11 (to which "upstream" is probably referring?) add/removing monitor still consistently causes for me some windows to move from one workspace to the other and, in particular, also causes windows inside a workspace to move even if the windows were on the the not-removed monitor. Not sure whether relevant, but this is with the nvidia drivers on a ThinkPad W530 connecting to various external monitors...
