[Bug] PathLayer is "fuzzier" after upgrading to deck.gl 9.2 when passing `useDevicePixels: true`

Description

Here's deck.gl 9.2:

https://github.com/user-attachments/assets/dc0098b0-30d8-46c3-a950-6816fe973223

Here's deck.gl 9.1:

https://github.com/user-attachments/assets/360032b2-6193-49fd-97dd-9b5efd6159bd

The only commit in between them is this Lonboard PR that upgrades to deck.gl 9.2.

Flavors

• Script tag
• React
• Python/Jupyter notebook
• MapboxOverlay
• GoogleMapsOverlay
• CARTO
• ArcGIS

Expected Behavior

No response

Steps to Reproduce

The easiest way to reproduce what I'm seeing is through Lonboard. It's this Python notebook in the Lonboard docs

git clone https://github.com/developmentseed/lonboard
cd lonboard
uv install
npm install
npm run build:watch
ANYWIDGET_HMR=1 uv run --group watchfiles jupyter lab

And then go to the north-america-roads.ipynb example

I'm really slow at making codepens because I don't work in JS often, so hopefully it's easy to spot what's going on 😬. Otherwise I can make a codepen in a follow up

Environment

• Framework version: 9.2.1
• Browser: Chrome 141.0.7390.54
• OS: macos 15.6.1

Logs

I get notes about This version of luma.gl has already been initialized, but I see those often and I don't think those are related.

Start with the Lonboard north-america-roads.ipynb example and reproduce the React rendering difference with useDevicePixels: true. Compare deck.gl 9.1 and 9.2.1 around the PathLayer behavior and confirm the result in the notebook; done means the layer has the expected sharpness after upgrading to 9.2.1.
