After moving from
{{{
linux-image-2.6.24-openmoko-gta02 20081103.git7172ec57-1
}}}
to stable-tracking branch (1b17c67794364bee) I noticed that sometimes
the touchscreen behaves as if it forgot to report a "mouse button" release
completely. If I then click something else then the "button" is
properly released.
Since I suspected that X or xvkbd (the only app where I have seen this
so far) could be the cause I ran evtest /dev/input/event1 for two days
in the background till the bug occured again. In the above log you can
see how touchscreen stays in the "mouse button is down" state for 38
seconds (1227651221.826158 to 1227651259.616190). That time was enough
for me to remove the extra plastic case I have around the phone to
make sure that nothing is touching the screen physically. However, the
touchscreen still would not report button release until I touched the
screen again:
