Steps to reproduce:

Upload an image into some chat on app.element.io

  1. register or login on app.element.io
  2. open a chat with someone
  3. either upload an image or paste it from clipboard

This is a regression that started a week or two ago on nightly. Works fine in the current beta/release versions.

Actual results:

The image is sent as a "regular" file and doesn't show a preview

Expected results:

The image should be sent as an image and show a preview

Thanks for the report! I figured out this is related to enabling OffscreenCanvas on Nightly (bug 1746110). Setting gfx.offscreencanvas.enabled to false in about:config makes the preview work again.
