When webcam active, cursor on textbox responding slowly

Hi friends!

I'm working with WebCam Library to capture an image. My UI also contains a textBox which allows user to name the image file in order to save the file.

I noticed cursor inside textbox is not responding accurately, since not all keydowns are registered while WebCam is started. I wouldn't like to stop the camera in order to allow user to keep watching what webcam registers while user is typing the image name.

I checked that if webCam stops, cursor in textbox is behaving as expected. Any suggestion will be welcome, thank you in advance!
