1456635 - Wikipedia tooltips flash at about 4 Hz

Status: RESOLVED WORKSFORME

(Core :: Layout, defect, P3)

Description

[MarjaE]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:59.0) Gecko/20100101 Firefox/59.0
Build ID: 20180323154952

Steps to reproduce:

Note: I haven't encountered the same bug on other sites. It may or may not occur on other sites. It is dangerous regardless. It is fast enough to trigger seizures, as well as falls and migraines.

I visited a Wikipedia page. I tried to select a disambiguation link ...


Actual results:

... but a tooltip popped up in front of the link, flashing, and blocking access to the link.


Expected results:

Rapidly-flashing objects can be dangerous, as well as painful and disorienting.

I don't think any objects should flash, especially at such speed, without user consent.

This seems to occur if and only if the tooltip loads under the cursor.

Some hazard on twitter.

I use my own font settings, which may affect the relative position of text and tooltips.

It's much harder to read without setting my own fonts and setting my own minimum sizes. Because forcing reasonable sizes using Firefox's font settings breaks many websites, with text overlapping text, or text hidden behind other objects, and because zooming breaks scrolling, I currently use Zoom Page WE to toggle font sizes, and this may be related.

Do this still reproduce?

No, but I've switched to using css for font sizes.
