Thank you Jacob for your suggestion,
for this application the choice of using eglfs is not under my
direct control, in addition to this I suppose that the use of X11 can
degrade the performance of the application (the target is a imx6
Single...).
Did you noticed a decrease in performance moving from eglfs to X11?
Which imx6 did you used? Single Dual or Quad?

Hi Jacob,
right, I did not specify that I use eglfs.
I can just talk from my own personal experience in using Qt5+iMX6. In
5.1.1, eglfs had a hard time tracking the mouse pointer, 5.2.0
improved things a lot. But best experience sofar has been in using the
X11 backend instead of eglfs.

Hi list,
using qt 5.2.2 (release branch from git, but I noticed
the same issue with 5.2.1) on I.MX6 it is impossible to flick
on qml elements, because the pointer does not "follow" the
finger on touchscreen...
The strange issue is that with non-qml application
(fingerpaint example) or using tslib test application
(ts_test) on device the cursor follow the finger at higher speed.
Is this a libqtslibplugin.so or a qml issue?
I generated the plugin without any option, only qmake, make
and make install...
I am using tslib library because my touchscreen does not
support evdev (it is resistive?); I mean, trying to use
EvdevTouch does not work at all, using EvdevMouse I see the
pointer moving on screen, but the click doesn't work...
Any suggestion will be appreciated...
Which qpa backend are you using, xcb, wayland or eglfs ?
