"Buggy touchpanel" error

[Conkey100]

I have installed version 1.20.41 on an old Android phone (Android 4.2.2). It seems to start up and connect to a pi OK, but after it loads and I've tapped on the touchscreen a couple of times I get a message stating "Detected buggy touch panel, enabling workarounds", then the touchscreen stops responding.

I thought this might be related to issue #28 and I tried disabling hover movements in the options, but that doesn't seem to have any effect. I've also tried the workaround mentioned in #28 (tapping in the same spot) - that just causes the "buggy touch panel" error immediately. I don't think it is the phone as the touchscreen seems to work fine in other apps.
