perf: Delay screen move for new tiles ...

[mmeeks]

If we have a visible screen-area movement (caused by a key-press(?)) - (and I expect @eszkadev or @gokaysatir can isolate where those occur). Then - in the case that we don't (yet) have all the tiles - we should probably defer the movement itself for some short period 50-100ms or until the tiles arrive.

I expect this would give a better visual / perceptual feel - and it is ultimately what the PC / desktop apps tend to do anyway - press a key, re-render the screen etc. =)

Not sure how easy that is to play with but - hopefully not too hard.

Try to find where the key press errors cause the screen movement and try mapping out the ui elements that is affected
