We are using Colibri IMX6ULL 256 with a viola carrier board
uname -r - 5.4.193-42221-gf78299297185-dirty
fw_printenv is attached
We have developed an application with Qt widgets, which works well when run from Qt over ssh
But when the same binary is run through wayland-app-launch.sh , we see lag on GUI but the GPIO and other peripherals work fine.
when a button is pressed (input GPIO), corresponding action takes effect immediately on output (GPIO). But the screen shows that after almost 2-3 seconds.
when touch input is given via touchscreen the action is reflected on GPIO immediately but the corresponding radio button switches after 2-3 seconds
As mentioned, the same application works fine when run via Qt creator over ssh
Please share the possible solutions, also let me know if you need any additional information
