Description
Hello QT team,
I have faced with a crash in HMI application. I use the QT_QPA_EGLFS_KMS_CONFIG environment for input devices with following configuration:
{
"outputs": [
{
"name": "HDMI3003",
"touchDevice": "/dev/input/event2"
},
{
"name": "HDMI3001",
"touchDevice": "/dev/input/event1"
}
]
}
After starting some touch operation was done with "HDMI3003". Application crashed with following stack trace:
