Poor responsiveness of Emteria 14.2.0 on Compute Module 4

I am using Compute Module 4 (8GB+32GB+WiFi) for a customer project. Have installed 14.2.0. The module is connected to a TFT 1280x800 10.1-inch display through HDMI and USB.

But find it to be very laggy and the touch response is also poor.

The performance is better when using Emteria 11.11.0 but still some lag is there.

When testing the same system with Raspberry PI OS, the performance is way better.

Please let me know if it is the current behavior and if not, how the performance can be improved.
