Data Panel Frozen on laptop display. Works on external display

jesusAAN3R — Mon, 26 May 2025 16:35:36 GMT

New laptop. Omen 16 2025. RTX4070m

The data panel is frozen if I open Fusion on my laptop display. It works if I open Fusion when a second display is connected.

I'm on latest Nvidia Drivers (576.52, May 19, 2025). Tried both studio and gaming. Windows is up to date.

Tried clearing Fusion cache.

Tried uninstalling, deleting everything related to Autodesk (including in the registry), reinstalling. Nothing works.

Nvidia Optimus is enabled on bios. Verified Fusion is using GPU 0 (Nvidia) in both cases.

Short of reinstalling windows, is there anything I can try? Thanks!

Thank you for your reply.
I've followed the steps for "blank data panel" as well as "data panel not scaled correctly". (Updated all drivers from the manufacturers site)
The only thing that works is disabling "Nvidia Advanced Optimus" in the Bios. This way, Windows only sees the Nvidia GPU and not the integrated one.

But this is not an acceptable solution, as my battery life will suffer, and sometimes I want to use Fusion with the integrated GPU.

Are there any other steps I can take?

I found a working solution here: https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/Fusion-360-does-not-start-when-launched.html

If I disable Nvidia GPU before launching Fusion, the data panel works! However, if I reenable it, it stops working.

However, creating an environment key "QT_OPENGL"-"software" has solved all my problems!

Fusion 360 now works both on external display and laptop display, and it uses Nvidia GPU in both cases.

Hi @jesusAAN3R, would you be able to include a DXdiag report so that we can attempt to reproduce the issue on similar hardware?

If you force use of the other GPU, does the issue reliably return?

Of course. Here is a DXDiag report that I generated while Fusion was open and datapanel not working.

For the record, the solution I used yesterday (Using environment key "QT_OPENGL"-"software") is not acceptable either because the panel is PAINFULLY slow to navigate.

So this morning I reinstalled windows from USB. Made sure all the drivers and device firmware were up to date, and windows applied all the updates. I installed Nvidia Studio drivers.

Then installed Fusion and, on this clean PC, the datapanel is still frozen.

I've narrowed it down to the dual GPU issue. If I go to Nvidia control panel, "Config display mode", and click on "Automatic Selection" or "Optimus", then Fusion crashes.
If I select "Only NVidia GPU", then Fusion Works.

This is only true for the laptop internal display. If I open Fusion on the second display, it works regardless of dual GPU mode.

I think this is related to the GPUs->MUX->Display topology on this laptop. It feels like the change from internal GPU to Nvidia GPU messes things up with some Fusion panels.

Interestingly, while Fusion is loading, I can see that the datapanel works and is also loading items. But a couple of seconds after that, the panel freezes.

I've also attached a FusionDiagnosticsLogs file. Hope it has useful information for you.

Please, tell me if there is any other information or report I can generate to help you reproduce this issue.

Thanks!

Thanks so much! Yes, it does sound like a dual graphics issue. In some configurations, I think external displays always use the dedicated GPU, so that would track with what you're seeing.

We're still investigating the exact cause of these dual GPU issues, but we've added some experimental options to try and alleviate them in the meantime.

Could you please try going to Preferences > Compatibility & Troubleshooting > change Qt Rendering Hardware Interface to D3D11 from Automatic. You can try OpenGL too, just to see what happens.

In addition, within the same panel at the bottom is a checkbox for Override Chromium GPU Workarounds - try checking this separately, as well as in conjunction with the Qt RHI override above.

I really appreciate you taking the time to try different configurations to narrow down the issue. To give you some insight, Fusion has a few different graphics systems in use at once: the canvas (Dx11, Dx9, or OpenGL), the toolbar and command UI (D3D11, Metal, or OpenGL), and embedded Chromium browser frames (ANGLE to D3D, GL, etc). They all have their own methods for detecting GPUs and different workarounds and shims for working with a given GPU; it could be causing Chromium and the command UI to disagree on the correct configuration, or it could be entirely isolated to the browser frame. We are improving our logging in this area to have a better understanding of the root cause.

Good news!

Changing Qt Rendering Hardware Interface to D3D11 fixes the issue.

Changing to OpenGL does not.
And checking Override Chromium GPU Workarounds does not fix the issue either (at least when Qt Rendering HW Interface is set to Automatic)

So with this fix, I think it now works 100%. I can open Fusion on internal or external monitor regardless of nvidia settings (automatic, Optimus or dedicated), and everything looks and feels super smooth.

Thanks!

Let me know if there's anything else I can do to help you gather more info.

Thanks for the confirmation @jesusAAN3R! Historically the default has been OpenGL, but in an upcoming release this will change to D3D11 so the override should no longer be necessary (but it won't hurt that you have it set forced to D3D11, just more of an FYI that "Automatic" will give a different result eventually).
