I’m using Rpi4b 8GB ram with Rpi 7" display. Its running balena blocks browser and launch URL set at [https://mfab-hmi-beta.vercel.app/](https://mfab-hmi-beta.vercel.app/). kiosk mode enabled GPU enabled, GPU memory allocated 512MB but still, the touch response is too slow. Kindly guide me on how to make it fast.  
Initially, I tried with the 2GB ram version then tried with the 8GB ram version but nothing improved.

@omprakash have you tried setting the env var `UDEV=1`?

You might also have to adjust some configurations if using a touchscreen. Take a look at this balenaDash setup guide in order to see how you might need to configure your screen: [GitHub - balenalabs/balena-dash: Build a Raspberry Pi based desktop dashboard for stats, photos, videos and more!](https://github.com/balenalabs/balena-dash)
