I noted resentment a small issue after use the multi-task function with some software on execution.

If you can't understand with the image, i can make a small movie for you check.
But basically the image get some frames bugged when you altering the desktop task.

Unfortunately, not even the screenshot shows it, but it's very strange that the wallpaper images practically break, with huge points that look like spears.
