Public bug reported:
A test app that demostrates this bug can be downloaded from here:
lp:~jpakkane/+junk/touchpad-tester.
My setup is that I have a Magic Trackpad and a Macbook Pro multitouch
trackpad. The test app prints out this:
Using device id 2, Virtual core pointer.
Potential device id 11, bcm5974.
Potential device id 13, Apple Wireless Trackpad.
If I use device ids 11 or 13, stuff works. Device id 2 leads to
problems, though.
I put down five fingers on one touchpad and then five on the other. Then
I lift all fingers up simultaneously. The end result is that I only
receive TouchEnds for roughly half of the touches. The others keep on
existing.
Possible reasons for this bug include X not sending touch end events or
X sending touch end events with a different device id than touch start
events.
Tests were run using precise.
