Thumbnail preview not showing

[pedro-h-marchesi]

Hi, there! Reporting this as I couldn't find an issue with this exact problem :)

1. Bug Report:

• BUG: When I hover over a thumbnail, instead of showing me a preview of the video to be played, either nothing happens or the preview buttons (Mute/Unmute and CC) keep appearing and disappearing (see attached example). This is seen in the query results screenm, in the Subscriptions screen and in the Home screen. Issue is not found inside the Channel nor in Related/Recommend videos when watching a video.

  • Browser: Google Chrome
  • HOW: 1-) Search for any word (e.g. "Beyoncé") / 2-) Hover over one of the thumbnails / 3-) Preview will not be played
• Did YouTube change? Not to my knowledge.
  • Or did our last update start the bug? This is my first time using the tool so can't report to that.
• Does the bug not happen when you log out of YouTube? The issue is also found when I log out of YouTube (however, it is then only seen when querying for a video, since Home and Subscription screens won't have any video to display).

More:

• *Expected /preferred behavior: Thumbnail to play when hovering on it
• ImprovedTube Version: 4.938
• Tested alone without other YouTube extensions or in incognito mode? Issue found even with other YouTube-related extensions disabled (Video Speed Controller, YCS, YouTube Captions Search). Issue also found when ImprovedTube is allowed in Incognito.

hi! & thanks @pedro-h-marchesi

• disabling "player_size":"custom" fixes this
• AFAIK we have another feature causing this bug (idk which, but non of those you enabled.)

lets add to the bug template, to test which feature might causes it. can we make the bug report template better otherwise?

---

• html names btw: the video tiles are called <div id="dismissible" (including related videos) once hovered, if they play, this appears: <div id="video-preview" class="style-scope ytd-app"><ytd-video-preview

Hi, @ImprovedTube, thank you for the swift reply! I'd tried disabling some features and didn't think the Player Size one could be causing it hehe I'll keep it disabled for now! Appreciate the clarification! :)

As for the bug template, I think that's a good idea! In case I run into another potential bug, I'll definitely test different features and try to identify if any of them could be causing it! ^^
