"Full screen repaints" stops working when HDMI plugged

Hi,
When I connect TV through HDMI cable to my notebook, "Full screen repaints" stop woking in the two screens and tearing appears.
Then to fix it, I have to run kwin and select again "Full screen repaints" (which was already selected!) and tearing disappears from both screens.

This problem is not present in other desktops (for example MATE, which I tested), so I guess it is Kwin and/or compositor related.

Any ideas? Is this a bug?

No answer since now...
Can anyone replicate this bug? Or I'm the only experiencing it?

I found this problem is already listed in KDE Bugtracking System:
https://bugs.kde.org/show_bug.cgi?id=363093

Since now, not solved!

Still this big problem, and the bug is "UNCONFIRMED" in the Bugs Tracking system: https://bugs.kde.org/show_bug.cgi?id=363093
This bug forces the user to set again the "V-sync" options of compositor after a screen is plugged, which is a very annoying thing and the opposed of "Plug and play" concept.
