Hi there ! This is not a Sencha conflict because I experience the same problem with my website (desktop version) shown on the iPad 1 and I don't use Sencha at all (only jquery). At very rare occasion, I had this phenomenum on Firefox 3.6 as well and on somebody else's website. We both used OL 2.10. I'm glad that it happens with the official Sencha example because I thought first I may have done some wrong programming with OL.
I have already spent a lot of time trying to fix this. Unsuccessfully so far. For me it's a critical bug. I'd like to develop a webapp instead of a native app, using OL and reuse almost all what i've done for the desktop version. Also I'd like to use the Sencha framework. This bug is reproductible on the iOS Simulator (choose iOS 3.2 in the settings of Dashcode to simulate the iPad). What happens exactly? First click on the layer button, bottom right of the screen (or the Search box, bottom-left button). A panel pops up, with a black translucent background. At that time, you can notice that the map is redrawing. After that (and only after that), during a dragging process, every time a new tile is loaded and displayed, the map seems to jump back for a quick time to the starting point of the dragging. I have also noticed that sometimes, tiles on the right border are stretched as if the first column of pixels is repeated along the horizontal axis. Moreover, since version 2.11 (from the trunk), the map shakes around the current position while being dragged. Also noticed on iOS Simulator (choose iOS 4.3 in Dashcode - simulates iPhone 4), the map flickers after all tiles seem to be loaded (not always, rather after a zoom-in). I ported the mobile-sencha.html example to Dashcode in order debug step by step in the iOS environment. I put a lot of breakpoints in Layer.js, Grid.js, Image.js, etc… So far, nothing found. When you put a transparent <div> on top of the map, does the map receive an event? Which one? Which handler? Digging into OL and trying to understand how the whole stuff works is quite difficult to me. So if somebody is willing to help and guide me through the debugging process, I am ready to spend more time.
