I have found probably two bugs in QTlockscreen. I haven't seen both of them before the "Slide Unlock" update.

#1
When rotating from portrait to landscape sometimes the screen locks in the landscape mode but on the portrait. It's kind of stupid explanation so here goes the screenshot:


#2
Sometimes when I slide to unlock the slider freezes on the way to unlock. It goes: Unlock by sliding, lock device, click power button to show screen, slider is in the middle. Maybe a qt freeze bug you've mention? Screenshot:


Someone can confirm this?
