Whenever I first open a game in studio, the viewport is completely visible and working fine. However, once I click Play Solo and then stop that Play Solo session, the viewport is completely blank and remains this way until I reopen the place.
This bug occurs every single time I do Play Solo and is hard to work with. My graphics card is a GTX 1080 and my processor is an Intel i7. If you need more specs, let me know.
@EncodedLua were you using OpenGL before the reset? There is a known issue with OpenGL and lua widgets that results in this exact behavior. That will be resolved in a coming update.
