Normally to deselect text I would click anywhere on the artboard, but this doesn't work after I highlight a part of the sentence and change color to it. I have to click on the text (because after using assets panel, artboard isn't active/in focus anymore) and only after that you can deselect it. Takes extra step which is annoying. It used to work fine in older versions.
Thanks for reaching out and sharing the video which was helpful. I tried replicating the issue at my end on my windows machine but I am unable to reproduce it. I would request you to please share the XD and the OS version of your machine. Does that happen with other text as well or with other files? Is it possible for you to share this XD file with me so that I can test it? If yes, please upload the file to a shared location such as CC or Dropbox and share the URL with me over a PM or here.
