    I am also getting this problem, setting executable focus back to our app eliminates the lag but it is not a good solution.

    This is a bad bug for our kind of application (Enterprise VR where we often have a VR client and a normal client with GUI running on the same PC, so the VR client isn't focused.

    We have found these repro steps also happen in 2018.3.2f1 and 2018.2.19f1

    Hope it gets fixed soon

    This problem must be a show stopper for some kind of games.
