Automatic fallback to software WebGL has been deprecated

L77 — Thu, 30 Jan 2025 21:05:20 GMT

I am working on recreating all of my web maps in experience builder. I was using Map Viewer Classic and Web App builder.

When I open a map in map viewer classic is loads okay. When I make a copy of the map and open it in the new map viewer the screen tiling is very slow and there is alot of lag visible in the screen. I thought maybe my map had alot of content, so I created a new map with only one point feature class that only contains about 1,200 points so it is a small dataset. It still renders very slowly.

I am working in google chrome and right clicked and clicked inspect and I saw this message in the console. Could this be the issue? I am not a developer at all and don't even know what this means.

Using Calcite Components 2.13.2 [Date: 2024-10-24, Revision: e38e2977d]

I attached a video showing how slow it is. I don't know how to fix this.

Here is a video showing how much faster it renders in map viewer classic. This video contains lots of layers , not just the one layer and it still loads much better.

Here is a pdf showing my computer hardware, it meets the requirements to run ArcPRro.

I'm on the same version of Chrome and I can't get the AGOL Map Viewer to trigger that error. More concerningly, the bug referenced in that message has been fixed a decade ago. Try some other maps (even if it's jsut a basemap) and try using other computers, I have a feeling your old Quadro is bugging out a bit.

@L77 @DavidSolari Pascal based GPUs are still well supported by Nvidia so other than making sure it is stable and you have updated drivers it will be fine.
ArcGIS Pro specs have nothing to do with AGOL performance so stay out of that rabbit hole 😉
(granted there is some overlap but you shouldn't need a 5090 to run New Map Viewer reliably)...

Deprecated does not necessarily mean unsupported (well, it can; but shouldn't be implied for things like this)

As many of us are experiencing bad performance in New Map Viewer in a variety of browsers have a look at the measurement ideas that are mentioned in the other post you linked this one to.

Layer complexity and layer source publication settings seems to drive this - and the point of impact bar was seemingly set much lower than in Classic Map Viewer.

Please continue the conversation in the other post where more people are involved already. If you can, share the layer sources - especially if they are public open data sources like the services I mentioned in one of my posts.

@RTPL_AU Thank you!

I emailed my IT department and they said that my hardware is in good working order, and they suspect that the issue lies with the web app too.

I will add more comments to the other thread. Thanks again for your feedback.

Hi,

Concerning Chrome Error Browser : "Automatic fallback to software WebGL has been deprecated"

Try Setting the following Chrome Flag to possibly make the error disappear:

Chrome Setting Name: "Bypass a blocked graphics card in Chrome"

In Chrome, do the following:

Type chrome://flags in the address bar.
Search for and Click Enable under Override software rendering list.
Restart your browser.
