I have two nearly identical systems, one is a pi 3 the other is the pi4. Both systems have the Raspberry Pi 7" display touchscreen.
Both systems are up to date on everything.
Both are running without a desktop environment.
I managed to follow instructions on https://kivy.org/doc/master/installatio ... n-rpi.html to get Kivy running on the pi4.
The pi 3 works fine with sliders and buttons. On the pi 4 the sliders and buttons work but the buttons always get a double hit when touched. They work fine on the pi 3. It is the same program on both.
Always two, so it isn't a bounce issue, and if I touch and hold, they both occur on button down not the release.
Both systems ~/.kivy/config.ini files are also the same.
Any ideas where to look or what to try?
