Comment 1 for bug 222164

I managed to fix this problem, which is confirmed by other users in some of the last posts of this thread

Basically, I edited the evtouch.c source file in such a way that screen_width and screen_height are swapped if there is a left or right rotation. Unfortunately, this doesn't fix the problem for resolution changes.
