Hello,
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.
e.g.
-
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
Thanks
