Since this post has some traction and I have some studio UI related bugs as well (along with the OP’s issue with random UI’s popping up when starting a test, which is usually just a visual annoyance than a workflow breaker). I will post some UI bugs that I’m also running into.
considering this might be related to plugins I’m wondering if this is also related to a plugin issue? I would often get docking issues where my viewport gets completely separated from my studio and leaving my studio viewport completely grey.
I had to hover my mouse over the viewport in my task bar at the bottom to get this picture, I can’t actually open it since it just brings me to a blank studio viewport.
This particular case happened on startup, but happens sometimes when doing a local server test with multiple players.
This can also occasionally happen when trying to dock certain tabs, usually plugin widgets which is mainly why I’m suspecting that this might also be a plugin issue (The first time this happened was actually with the animation editor plugin just yesterday).
What I also noticed that started happening which gets kind of annoying is whenever I open a script that isn’t already opened, it opens in a very small tab undocked
And very often when I open back up my studio session after having closed it, all my script tabs that I had kept open for my workflow have all been forcibly closed, and sometimes even reverting a few lines of code. This hasn’t been super serious yet but still cause for concern.
This heavily affects my workflow since I sometimes have to re-open studio several times to get it to load properly. Scripts forcibly closing is really annoying and breaks my setup every time and having my scripts open in a small box seems super unnecessary. I’m going to try and disable a few plugins that I suspect might be causing it but its still something I wanted to mention along with the other UI bugs.
Edit: I disabled all plugins that uses the Widget feature, at first my studio still had an undocked viewport that I couldn’t open but eventually I was able to open up my studio session as normal. So it does seem like this might also be a plugin related issue. The script opening as a box still sometimes happens.
