Strange behaviour with lock screen with multiple monitors

Hello,

I don't remember if that happen before (I don't think so) but when I lock the screen, the unlock box appears on all monitors. As far as I remember only the main monitor displayed the unlock box, the rest of monitors didn't show anything.
Is this some kind of bug?

Regards.

4.10 introduced a new screen locker written in QML, and it seems to still have some issues (e.g. with keyboard focus). Not sure if appearing on all screens is intentional or not though, you can try searching http://bugs.kde.org and see if it's been reported.

From what I've seen It seems to be some king of bug.
Can I bring back the non-QML version?

You can use a traditional screensaver (including blank screen), and that should work, IIRC. You can set the option in System Settings > Display > Screen Locker (check "Screensaver").

I tried it but unfortunately It doesn't work.

How exactly it doesn't work? It's not displayed, or does the QML locker still appear?

Yes, It's displayed but when you press a key the QML locker still appears.

Is there any issue with actually using the QML Locker, or is the only behaviour at issue here being the display of it on multiple monitors?
If this is the case, I suspect it may be desired behaviour, with the old behaviour being a bug caused by assumptions made by the old screen locker.

So in your opinion it's a "normal" behaviour to show the screen locker on all the screens as if they were independent lockers?
I mean, if I write in one of the screen lockers the normal behaviour should be to show in the other ones that I'm writting in one of them, shouldn't it?

There is a lock interface on each screen, yes. This ensures that no matter which screen is on/off or which screen your mouse/keyboard focus is on there is a dialog. That it is done in QML is not relevant to this; if it were done with QWidgets it would be the same, so let's not get distracted by that implementation detail.

Can you provide more details why this is an issue for you?

It's only my opinion, I have the feeling that there are running 3 independent processes even though there are only one. That feeling comes when I see that what I write in one box doesn't show in the other ones, and as I previously said, would it be more "natural" to get the same input on all the screen lookers at the same time?

By the way, why doesn't the text line automatically get the focus when a key is pressed?
