When we type on the text field at the LiveCycle Design ES2 view of Designer we are getting much delay between characters. Is there a way to fix this? We even tried AEM forms version 6.4.0 which is compatiable with windows 10 has the same thing happen as well. The keyboard layout is en_US and for the installation layout is en_US.
I find when forms have a lot of images and have set the "Embed image data" option things get slow very quickly. You should only have Embed image data set if you have a number of developers working on the form and they don't have a shared location to store the image. Happy to see if it's a problem on my machine if you are able to share the form. Just upload it to a file share site and post a link to it in this thread.
