Description

In a E2E room with a friend that has long history, hovering over thumbnails of images I send them freezes Firefox and causes 100% CPU of the firefox process

Steps to reproduce

  • Have room with long history (I tried a new E2E room with a dummy account with no history and was unable to reproduce)
  • Send images
  • Hover over the image preview thumbnail
  • firefox process will have 100% CPU usage

I also tried the same with Riot Desktop on my OS X machine (10.11.6) and was unable to reproduce

Version information

  • Platform: web

For the web app:

  • Browser: Firefox 59.0.2
  • OS: Void Linux
  • URL: riot.im/app
