This is no longer an issue after the update to Firefox for Linux v. 89.0 that came out today.

i can’t reproduce the problem. are you using some extensions on your browser? [image]

I can’t replicate either. Tested on Windows 10, 64bit with latest Firefox 88.0.1, 64bit. @wouterkoch Try testing it in a private window (Options button → New private window) which will disable extensions and will open the browser in a “clean state”. Also, it’s helpful to know the operating system …

I can reproduce this issue in Firefox 88.0.1 on Arch Linux. Setting the opacity to zero also fixes the problem. Running the browser in safe-mode makes no difference. I thought that the exact behaviour of opacity could depend on the system’s compositor implementation to some extent, which might have…

I can also confirm this in Firefox 88.0.1 64-bit on Linux Mint. This has been going on for a few weeks now - I was hoping it would go away before I got around to reporting it :grinning:. I just checked for it in Chrome 90.0 on Linux Mint - no problem there.

in Firefox on Linux, if you go to Help > More Troubleshooting Information, what is the User Agent string that you see? is it something like below, or is it something else entirely? Mozilla/5.0 (X11; Linux x86_64; rv:10.0) Gecko/20100101 Firefox/10.0

On my machine: User Agent Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:88.0) Gecko/20100101 Firefox/88.0 OS Linux 5.4.0-73-generic #82-Ubuntu SMP Wed Apr 14 17:39:42 UTC 2021

I tried temporarily downgrading to Firefox 87.0 and the problem disappears. So this seems to be caused by a recent change in the Linux version of Firefox. Since it’s just a minor cosmetic issue, I decided to use the Stylus Add-on to fix the problem for myself. This is what I used: @-moz-document do…

I was offline for a while there, sorry. By now it seems to be confirmed by others that this does occur on FF 88 for Linux, thanks for confirming! The provided screenshot was already taken from a private browser session. User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:88.0) Gecko/20100101 Fir…

I suspect this was done to prevent issues with something like the screenreader ChromeVox, which skips rendering of anything with opacity: 0; altogether ( https://github.com/michalsnik/aos/issues/397 )

Yes, I reached the same conclusion. There’s a fix related to screen readers mentioned in the Firefox 88.0 release notes that seems pertinent.
