--- Comment #5 from Wilson wilsontulus5@gmail.com --- After more tests I've confirmed that Wine-Staging is not required to run Studio and create new / open an existing game. The situation before applying the patch is better than the time i've reported this, although the script editor and the top notification bar isn't getting any better without the patch applied.
