[Bug] Fusion 360 becomes unresponsive after launching on secondary display

I have personally experienced this issue and found that the solutions in this thread work for both F360 and Ultimaker Cura.

Users on the Cura Github have suggested that updating the version of Qt used might be a possible solution to this issue

Please check to be sure you have the latest Fusion 360 version. Under Help > About, there is a build number. It should be 2.0.8624 right now.

I'm asking this because I cannot reproduce the issue, and Fusion is already using that version of QT. Please let me know what you find, glad to track down the problem with you.

Hi Phil

Thanks for the reply. I can confirm that the issue persists on version 2.0.8624. Launching on my secondary display causes the unresponsiveness but if I can move the window to my primary display in time, it launches fine.

Cheers

Hi @Anonymous, would you be able to take some process samples for me to share with the dev team?

You can do this by accessing the Task Manager, go the the Details tab, right click on a task and click Create dump file.

We are looking from samples from a few files, from both Fusion 360 and Cura, to compare.

1. The Fusion/Cura.exe itself, when frozen at startup
2. QtWebEngineProcess, under the same conditions as (1)

QtWebEngineProcess is part of the underlying GUI framework, but uses OpenGL instead of DirectX, so both processes may give us different indicators.

The files produced by these process dumps can be quite large, sometimes 500MB - 2GB - I recommend uploading them to your A360 drive and sharing a link to keep things easy.

Thanks,

Lance

I've uploaded them to A360 but I don't see how to share a link to the folder. It's in the Demo Projects folder under Dumps. Here's the page URL from my web browser if that works?

Give this a try - navigate to the file Overview within A360. Next to the File Size should be clickable text that says Share Link: On/Off. That should open the sharing panel (you might need to play with your browser filter/blocking for it to display).
