Why does dragging a card double its size in Firefox?

[Jayen Ashar]

I've been having this weird issue for about 3 months.  When I drag a card, the card doubles in size and I can't see where I'm dragging it.  It happens in private browsing in Firefox so it's not related to an addon.  It doesn't happen in Chrome.  It does happen across all my Atlassian accounts, so not related to a new feature being slowly rolled out.

@Jayen Ashar I am not able to recreate this.  What version of Firefox do you have installed?  Is it happening on multiple computers in Firefox?  Have you cleared your browsers cache?

It's Firefox 119.0.1 today but I'm sure it's been happening for a few versions.

I just tested on another computer.  It has Firefox 120.0 and not having a problem.  My Firefox is set to dark mode and the 2nd computer is on light mode.  I also notice that the card is partially transparent on the 2nd computer but I don't think I've ever seen that on my computer.

I did not clear my browser cache as private browsing ignores the cache.

I did just test on a new Firefox profile on my computer (v120.0) and it has the same issue.

I just tried switching to light mode and it has the same issue.

I checked Chrome again and the card isn't partially transparent.

Can it be related to my graphics card or something like that?

Thanks for looking at this!

@Jayen Ashar it sounds like a CSS issue.  I would still recommend clearing cache and seeing if that fixes the issue.  Also are you sure there are no browser plugins installed?

[Jayen Ashar]

There are no browser plugins enabled for private browsing and no browser plugins installed in the 2nd Firefox profile.

The cache should be clear in private browsing and is definitely clear for the 2nd Firefox profile.

window.devicePixelRatio is 2 in case that is related.

@Jayen Ashar I have tried recreating the issue and I am not able to.  It has to be something with your browser on the machine and I would still recommend clearing the cache just to rule it out.  You might have to uninstall and reinstall the browser, especially since it is working on other computers.
