    Unity finally introduced fullscreen game view in the editor, but the feature is useless as long as this bug persists. The game view fullscreen feature is not available in 2022.2, perhaps for this reason? I want to do video projection mapping on external displays (video projectors) from the editor. At the moment I have to build every time I want to make adjustments.
