1758015 - Scrollbar is visible in YouTube fullscreen mode

Status: RESOLVED INVALID

(Web Compatibility :: Site Reports, defect)

Description

[Kagami Rosylight [:saschanaz] (they/them)]

YouTube hides the scrollbar in fullscreen mode but it's now visible whenever moving mouse or scrolling the page.

Turning on "Always show scrollbars" Windows option and reloading the page fixes it. (Without reloading it still shows the scrollbar.)

Strictly speaking I don't think it's that patch that regresses this, but mozregression blames it anyway for a reason, so 😉

Set release status flags based on info from the regressing bug 1757647

This happens on other platforms with overlay scrollbars as well, and AFAICT is working as intended, as the page is scrollable. See also https://bugs.chromium.org/p/chromium/issues/detail?id=1290227 which is the equivalent Chromium issue (also WONTFIXed).

If YouTube wanted to hide the overlay scrollbars they could use scrollbar-color: transparent transparent;. Maybe we should contact with that suggestion them if you feel strongly about that? We have a mailing list with them IIRC.

(I think it's more like WONTFIX than INVALID)

If the cursor is at the right corner the scrollbar never disappears, and that's a significant behavior change which will disturb users. Probably worth pinging them, but I don't think I know anything about scrollbars. I can start a thread and then maybe you could add more info. Does that sound good?

BTW, does this also happen on macOS?

Sure, sounds good :)

Yes.

I can't confirm this happens on Edge Dev, that flag doesn't give me the overlay scrollbar at all 🤔. Can you? I'd like to say "this affects both Edge and Firefox, we need to fix it".

I can probably confirm tomorrow. But anyways just pointing to the Chromium bug should be enough.

[Kagami Rosylight [:saschanaz] (they/them)]

Hah, never mind. I just got the Canary build and I can confirm that it's still an issue there.

Let me try to reach out to YouTube.

Ah, sorry, Kagami already did, this is filed internally at Google as b/224524055, for future reference.
