[Interest] Touch frozen in Qt 5.15.9

[Ramakanth Kesireddy]

Hi,

We are using Qt 5.15.9 commercial license with Yocto Dunfell configuration
using evdev touch plugin on IMX6 based device.
Here are the exported environment variables being used:
export QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS=/dev/input/event0
export QT_QPA_PLATFORM = eglfs

However, touch/UI freeze issues are being seen intermittently.

Any recommendations on the environment variables if required to use export
QT_QPA_EVDEV_TOUCHSCREEN_INPUT=/dev/input/event0 instead or any known
issues in Qt 5.15.9?

Appreciate your inputs in this regard.

Best Regards,
Ramakanth
