Updating the GUI in the main thread can cause noticable delays in the user
interface. The progress bar is a good example. If you update that from the
main thread, then every time the main thread has to repaint the progress
dialog, it's going to interrupt the user experience.

Animation and VR simulations that require rapid repainting of the display
are another area where you often don't want to tie up the main thread by
forcing it to handle the paint requests and such. The application can
become extremely unresponsive if the main thread has to handle such paint
intensive tasks.
