This seems to be happening to me since the latest major Fusion 360 update. When I am modeling in Fusion, the Fusion 360 window frequently loses focus during or after calculating a feature. This seem to happen the most when a feature (like a medium-sized feature pattern) takes enough time that Fusion shows the spinning blue circle indicating that Fusion is computing the result. My window shifts to another application window that happens to be open, such as my Chrome browser or the Windows file manager window, or any other application that I may have open. I am on Windows 10 Home, version 21H2, OS build 19044.2604, with Windows Feature Experience Pack 120.2212.4190.0. My computer is an HP Envy m7 notebook PC with an Intel(R) Core(TM) i7-5500U CPU @ 2.40GHz 2.40 GHz, 12 GB RAM, and an NVIDIA GeForce 840M card with 2048 MB of GPU RAM.
Same here. It happens when Fusion interacts with the local file system to save down a file, e.g. exporting, save as mesh etc. My browser window immediately jumps to the foreground at the point of hitting Save in Fusion. Doesn't appear to happen when overwriting an existing local file, only when creating a new file.
This happens to me all the time. I'm running Windows 10. Happens on both computer I use. I have a lot of RAM; my laptop has 48 GB, desktop has 64 GB.
