Canvas-based video preview not rendering correctly in Microsoft Edge

[borja1990]

Hi XBVR team,

First of all, thank you for your continued work on this project — it's an incredibly valuable tool for managing VR content.

I’ve encountered a rendering issue when using XBVR in Microsoft Edge (Chromium-based). While direct playback of .mp4 files works fine, the canvas-based video preview used in the UI fails to display correctly. Specifically:

Videos play normally when rendered via the < video > tag.

Previews rendered inside remain black or frozen.

The issue is specific to Edge; Chrome and Firefox behave as expected.

This seems related to how Edge handles canvas rendering — possibly due to GPU acceleration or sandboxing differences. I understand Edge isn't the primary browser for most users, but given its Chromium foundation, it would be great to ensure broader compatibility.

Would you consider adding a fallback option to use

I'm happy to provide system details, test files, or help debug further if needed.

Thanks again for your time and dedication!

Confirmed: previews render perfectly in Chrome (fresh install, default settings). Edge still fails even in incognito mode and with hardware acceleration disabled. Likely a canvas/WebGL rendering issue specific to Edge.
