Hello,

I am encountering a unique issue with the touchscreen on our custom 5728 board. We have a custom board that runs the Weston display manager, and we've configured a Qt application to start automatically after every boot.

The problem we're facing is that, in about 2 out of 10 boot cycles, the touchscreen does not respond to our Qt application, although it does respond to Weston's default applications like the Weston editor and terminal. We have used the "evtest" tool to verify the touch inputs, and it seems that the touch events are being detected properly with no apparent issues.

We are using:

Weston version: 2.0.0

Qt version: 5.9.7

Touchscreen driver: ar1021

Regards,

Swaroop Muralidharan

Hi and welcome to devnet,

Qt 5.9.7 is obsolete. One thing you should do is test a more recent version of Qt.

You might also want to enable all debugging output of Qt to see if something comes out of it.
