Hi, 5.15.9 is quite outdated (current is 5.15.16). A number of known touch-related issues have been fixed with https://codereview.qt-project.org/c/qt/qtbase/+/516578, included in 6.7. Touch handling has been seen major improvements in Qt 6. If the issue persists with a more recent Qt Version (I'd recommend 6.5), please file a bug report with a precise description and a minimal, compilable reproducer.

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? Regards, Poonam
