lagging in the interface

When using Pharo under tablet (both iPad and Android), we have noted
some lag in the user interface when clicking a button. Indeed sometime
you have to press twice a button to get the press event caught by Pharo.

This problem does not occur with Squeak 3.9 and same StackVM.

Any idea?

Not really, it is just that some time, tapping on a button may just not
respond.
Dimitry reported me it was not occuring with Squeak 3.9, but I have not
tested it myself.

At first I though it may be related to the theme I use for DrGeo, but
Dimitry noted the same issue with bare bone Pharo.

Re: lagging in the interface

apparently this is about even delivery mechanism and/or with interrupt handling.
but i cannot say any more details, because i have no idea how this is
handled on ipad (and it is handled differently for sure,
than on other platforms)

Aye, almost certainly a VM issue (or VM interaction with image)
