Constantly blinking busy cursor after December update

[Anonymous]

After an update few weeks ago, my cursor constantly blinks the busy cursor when Fusion 360 is open. From my work history I can see that this was update was released somewhere between november 26th and december 12th, I'd guess it was much closer to latter.

The bug appears even when I have uninstalled Fusion360 with your cleaner and installed it again without even logging in.

I can trace the problem to "AutoCAD component", or AdCefWebBrowser.exe. It takes 1-2% CPU load while idle and if I kill that process, the cursor returns normal. But obviously this isn't solution, because then data panel goes blank. My CPU is 6700k, so that ~2% is pretty heavy load for an idle process.

The cursor keeps blinking even when Fusion360 isn't the active window. It doesn't affect performance, so I can still do most important tasks just fine, but that blinking does cause a headache if I try to work with it any longer period of time.

Hi @Anonymous,

Welcome to the Fusion 360 Community!

Just to check, what kind of computer do you have and what is the OS.

I have seen a few times that is specific to Windows 10 and not necessarily Fusion per se. (Fusion is triggering it, but it is a Win10 setting). 

Do you have an HP model? If so, do you have an app called SimplePass?

If not, can you try, opening up your Mouse Properties (if you go through settings as opposed to control panel, you will have to click More/Advanced Settings).

Once the dialog is up, can you hover to the Pointers tab. Select the "Working in Background" Option and select Browse. Choose aero_arrow as the symbol and hit OK.

My guess is that since the Data Panel is a chrome extension and is constantly syncing, you are seeing this as the browser is refreshing or syncing. I am not too sure however. Let me log this with development to test as I don't see this on my Win10 machine.

Thanks,

Thank you for quick response. I have custom build PC with latest Windows 10 Pro.

But your answer did inspire me to dig deeper and test confilicts with seemingly unrelated programs and settings. And I did finally found the second party of this issue: MSI Afterburner & Rivatuner Statistics Server. They are co-existing pair of software for monitoring and controlling GPU. If I close them and restart Fusion360, the bug disappears. Even the CPU load of whole Fusion360 drops to 0%, as it should in in idle.

Weird thing is that Afterburner and RTSS have always been installed on my PC and I didn't update them when this bug appeared. So I'd still say that recent Fusion 360 update did trigger this bug, eventhough the underlaying cause might be one of those two programs.

So my problem is now solved and you may ingore this bug if you want. I'd still recommend developers at least check if there was a clear mistake somewhere, but the bug clearly isn't as big as I previously thought.

I just want to chime in and say that I have the same issue with the original thread creator. My cursor was constantly refreshing when I started my computer. I have an MSI GT72 Running Win10. I believe we have the same issue as the person that started the thread. I troubleshoot my laptop with the recommendation of Microsoft support to do a clean boot https://support.microsoft.com/en-us/help/929135/how-to-perform-a-clean-boot-in-windows. I was able to pinpoint that the problem was the Autodesk Desktop app. On the support website, it said to disable all the startup application and one by one enable them. When I enabled my autostart for Autodesk Desktop App the problem persist. I disabled the auto startup and its normal again. Bugs maybe present on the new update.

I got new ping from this topic, so I want to share my latest findings about Rivatuner.

With up-to-date versions, I haven't seen this problem with Fusion 360. But I have had few similar problems and the solution isn't to close those programs but add excetion in Rivatuner.

Add the executable to the Rivatuners list and change "Application detection level" to None. Then it shouldn't cause any problems with that program

Fusion 360 executable is weird, because it doesn't install like standard program. It installs to AppData so that it can autoupdate more easily. The path is C:\Users\*username*\AppData\Local\Autodesk\webdeploy\production\*randomid*
