Bug: "Create Drawing" crash on 4K screen - with reproduction

[Anonymous]

Screencast showing reproduction with a 3840x2160 monitor: https://autode.sk/2Rq16dc

1. Create a body
2. Save design
3. Create drawing
4. Click OK on dialog
5. Wait for drawing to open
6. Move mouse -> drawing crashes (closes itself without any error)
7. Change to any other resolution (I did 1920x1440 in the recording, but e.g. 1920x1080 and 2560x1440 work too so it isn't an aspect ratio issue)
8. Repeat steps 3-6 -> works without issue

Various workarounds I discovered over the last few hours troubleshooting:

1. Change to a different resolution (as demonstrated here)
2. Disable NVIDIA driver (device manager -> display adapters)
3. Attempt to record the reproduction while running Autodesk Screencast locked to Fusion 360. To be clear: the bug does not occur when recording locked to Fusion 360, whereas it does occur when recording the full screen as shown in the screencast linked above. Yeah, that made recording this reproduction confusing.

Troubleshooting attempts:

• Tried clean installs of Fusion 360 - both via manual steps listed in help docs as well as the auto cleaner program
• Tried clean installs of multiple GPU driver versions including both Studio Ready and Game Ready. Versions tested: 462.59 (current Studio Ready version), 466.27 (current Game Ready version), 466.11, 465.89, 457.09, 442.92
• Cleared temp data
• Rebooted a half dozen times at various points, e.g. while reinstalling Fusion and GPU drivers

This is reproducible with more complex designs as well. I attached Fusion 360's logs as well as dxdiag containing system info. I'm a software engineer so I'm comfortable doing more troubleshooting, testing, Zoom meeting, etc if needed to solve this.

Hi caleb,

We have not had other reports on this - sounds like you have already tried what I would have initially recommended (e.g. upgrading the video driver). When it crashes, are you ever presented with a CER (customer error report) dialog? If so please send them in, and post here the CER number that you get back. That would be a big help.

In the meantime, I do have access to a 4k monitor, and will try to repro myself, athough it could be graphics-card specific.

No CER, unfortunately. I agree with your suspicion that it's likely
graphics card specific... I'm able to reproduce it so trivially on a common
use-case that you would have had a ton of bug reports by now otherwise.

If you know of any way to get more detailed debug logging I'm happy to do
so. I don't do any graphics programming in my work so not very familiar
with the stack, but is there possibly a way to trace DirectX calls or
something like that? And to save you digging through the dxdiag file again,
I'm on an NVIDIA GeForce RTX2060 (original/non-super).

Looking at DXDIAG, the first thing that jumps out at me is DirectX 12. Is it possible to drop down to Dx11, and try that? If that works, would that limit how you use your display?

I tried changing the Fusion 360 setting "graphics driver" (in preferences -> general) to each option with a restart in between, they all have the same broken behavior:

• Auto-select (which was the default)
• DirectX 11
• DirectX 10
• OpenGL Core Profile

I also looked through NVIDIA's control panel and didn't see an option anywhere there. I don't think there's an OS-level setting for this either from a quick bit of research. Is there some other way to set it that you're referring to? If there was a way to drop to DX11 I think that would be acceptable... I do some gaming and photo/video editing on this computer too but I think everything still ships with DX11 support these days so that shouldn't be a problem.

Hi caleb,

We released a Fusion update yesterday and it included a fairly large change in the drawings code. Would you mind checking your setup with this newer version? I am very curious to see if it is better, worse, or the same. In the meantime I will look into how to force Drawings to use Dx11 - you are right, I don't think Fusion's preferences affect Drawings.

Hi caleb,

If the latest Fusion update has not resolved this issue for you, I would like you to try something else to help us diagnose the issue.

Right-click on your Windows desktop, choose Display Settings. Take a look at the Scale value you have, and try scaling up. For example if you are at 100%, try 200%. Now, this will mean that UI elements and text get larger, while the screen resolution remains at your original setting (something like 3840x2160). It would be interesting to hear if this resolves your issue. Thanks, and we will continue to try to reproduce it here.

Sorry I've been busy. Looks like the drawing-related update fixed this for
me fortunately!

I assume you mean the latest Fusion update? Very good to hear.
