Full-screen preview window bug

I would like to point out a bug that I have found in the Resolve 15 studio beta 5.

When I use the full-screen preview of the video, in "Color" tab, sometimes the playback buttons disappear, and it is impossible to go back to the main window.

Indeed, the program does not respond to the "esc" or the other keybord commands: also, it is impossible to save the project, when the program is in this condition. The only solution is to terminate the program, by losing all the unsaved modifications applied to the project.

I can confirm this. It has happened to me as well, though i am not sure what the conditions that produce this behavior are.

BM have responded to a similar Bug report in the last couple of days (it is likely this will be fixed in the next Beta).

In my experience you can break out of this by:
1) Save project
2) moving the mouse to the top of screen switch project (WHICH BREAKS out of FULL SCREEN)
3) Switch back to the project you were on before the swtich.
