Dear Corona-community,
what’s going on:
In one of my scenes I have 4 scrollviews, each with roundabout 20 display.newImages and a couple of imageSprit-objects. Each scrollview is as wide as display.contentWidth and they’re placed next to each other. So only one of those four scrollviews is visible, the other three are outside of display. By swiping to the left or to the right, the visible scrollview gets dragged outside of screen and the scrollview left or right to the current visible scrollviews is dragged onto screen.
what’s the problem:
When I launch my app, both scrolling within a scrollview as well as switchting between the visible scrollview is smooth and soft. But when my display goes into sleep and I reactivate it, I see heavy lags. Scrolling withing the current visible scrollview is very laggy, also switching between the scrollviews doesnt happen in a smooth way. As soon as I scrolled though all four lists, speed is fine again.
Does anyone know why this is happening - or even know what to do against that behaviour? To me it seems like my phones are all capable of scrolling smooth hardwarewise since at initial app-launch everything runs fine - unti the app suspends.
Any ideas? 
Thanks,
Chris
