 larsman on Discord asked to file a bug report about this.

 I'm not a regular user of the iOS port, but it's been reported that the
 default iOS controls (i.e. "touchpad mode") became unusable since iOS 16
 was released.

 (At first we thought it could be related to
 https://9to5mac.com/2022/09/15/ios-16-bug-three-finger-games/ but
 upgrading to iOS 16.1 didn't solve the issue.)

 I can confirm this with iOS 16.1 running on an iPhone 8 Plus (built with
 Xcode 14 and just following our iOS build documentation, on current Git
 HEAD):

 * the (default) "touchpad mode" controls are almost unusable: whenever you
 do a single-tap somewhere, the cursor will move away by a significant
 amount, and so it's almost impossible to hit any button or do any
 point-n-click action (as if using a really poor touchscreen)
 * "Non-touchpad mode, mouse, Magic Keyboard and game controllers seems to
 work properly" (larsman)

 Unfortunately, my only iOS device has been updated to iOS 16 and so I
 can't test iOS 15 back to confirm whether this is an iOS 15 => 16
 regression. I can't reproduce this issue in the Xcode iPhone simulator,
 though.
