This has perplexed me for over a year at this point. The only page I have run into this issue on is https://create-react-app.dev/docs/getting-started and the animated SVG, but I imagine it would occur elsewhere if I ever ran into animated SVGs. Rather than try to describe it, I have included a screenshot of what I see (screencap is just a single frame, of course) It animates, but it's like it is offset or only renders every other line or something. I don't know if this is the right place for this, but thought I'd try. Here are some browser specs: ``` Name | Firefox -- | -- 130.0.1 20240913135723   release Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:130.0) Gecko/20100101 Firefox/130.0 Windows_NT 10.0 22631 Enabled Application Basics ------------------ Name: Firefox Version: 130.0.1 Build ID: 20240913135723 Distribution ID: Update Channel: release User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:130.0) Gecko/20100101 Firefox/130.0 OS: Windows_NT 10.0 22631 Launcher Process: Enabled Multiprocess Windows: 1/1 Fission Windows: 1/1 Enabled by default Enterprise Policies: Inactive Google Location Service Key: Found Google Safebrowsing Key: Found Mozilla Location Service Key: Found Safe Mode: false Memory Size (RAM): 15.9 GB Disk Space Available: 280 GB Pointing Devices: Mouse Crash Reports for the Last 3 Days --------------------------------- Firefox Features ---------------- Name: Firefox Screenshots Version: 39.0.1 ID: screenshots@mozilla.org Name: Form Autofill Version: 1.0.1 ID: formautofill@mozilla.org Name: Picture-In-Picture Version: 1.0.0 ID: pictureinpicture@mozilla.org Name: Web Compatibility Interventions Version: 130.2.0 ID: webcompat@mozilla.org Name: WebCompat Reporter Version: 2.1.0 ID: webcompat-reporter@mozilla.org Remote Features --------------- Remote Processes ---------------- Type: Isolated Web Content Count: 3 Type: RDD Count: 1 Type: Preallocated Count: 3 Type: Extension Count: 1 Type: GPU Count: 1 Type: Socket Count: 1 Type: Privileged About Count: 1 Type: Utility Windows Media Foundation Count: 1 Type: Utility JavaScript Oracle Count: 1 Type: Utility Generic Audio Decoder Count: 1 Graphics -------- Features Window Device Pixel Ratios: 1 Compositing: WebRender Font Visibility Debug Info: Windows Platform Asynchronous Pan/Zoom: wheel input enabled; scrollbar drag enabled; keyboard enabled; autoscroll enabled; smooth pinch-zoom enabled WebGL 1 Driver WSI Info: outOfProcess: false inProcess: true EGL_VENDOR: Google Inc.
