While working on a project today, I found that performance would get worse and worse until I restarted the app. I could go around 15 minutes before Fusion became unusable. Simple elements, like tooltips, took many seconds to draw. You could watch the images in them load. After five or six cycles of that, I sat down and found reproducible steps:
1) Make a very simple document. The sample I've shared is an extruded 10mm square.
2) Save it to a project that has a few items in it. The one shown below has maybe 20 or 30, although I first saw this happen in a directory with maybe 8.
3) Make sure the data panel is open to where your file is saving
4) Change the heigh to the extrusion and save it again.
5) Do this five or six times
Eventually, the app becomes so slow it starts to trigger all the usual "too much compute" nonsense. The component browser turns black. The %$&@ app window backgrounds itself.
The only way to improve performance is to restart the app.
