User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

Applied a "filter: drop-shadow(.05em .05em #f35135);" CSS rule to three lines of sans-serif text. However, whenever I select a one of the bottom two of these lines the "shadow" cast by the text in the line above suddenly has square pieces missing from it. (Please view attached screenshot.)

Actual results:

The drop-shadow effect on the above text became jagged / had square cuts in it.
(See the bottom right of the text "Russo" for the artifact.)

Expected results:

The text simply should have been selected. On another web page I am working on it appears to work fine within Firefox. Nearly no differences between the two groups of text between these pages however.

*Edit: I also noticed that at the bottom of the "R" there is a square corner sticking out of the leg of the letter's "shadow" as well.

Hi @Anthony Russo, please provide a TC, link or something in order to test the issue. Further, I will add a component, if isn't the proper one please fell free to change it.
Thanks.

Also please provide the output from "about:support".

Jonathan - any suggestions about who could look at this?

I think Markus may know more about filters, IIRC.

Above is a link to a page that demonstrates the problem from my Firefox browser.

Liviu mentioned something about adding a component, I wouldn't know what he meant by this. Could anyone clarify? Thank you.

Let me know if there is anything else you need from me.

I am getting a 404 error when I try to hit: https://cs.csub.edu/~arusso/blog/practice/practice%20one.html

I apologize, I had moved the file location. I have gone ahead and copied the content to a new link that I will leave alone for your troubleshooting. https://cs.csub.edu/~arusso/blog/bug%20report/home.html

@Anthony could you please try to re-test the issue with WebRender off?
I've tested again the issue on Windows 10
Firefox Version 68.0.1
Build ID 20190717172542
AMD FX(tm) -8320 Eight Core-Processor

  • I've tried with WebRender on/off => same result; cannot reproduce the issue- I will attach a screenshot to see how it looks in my end.

Attached image bug-1571255.png

Two things: first, enabling webrender seems to have resolved the issue (by default gfx.webrender.enable was set to false).
Second, in the screen shot you had provided I did notice the visual artifact and have outlined it in the screenshot below. Was webrender disabled at the time of this screenshot? I have also provided a small screencapture of the text after I had disabled webrender again. Let me know if there is anything else I can do.

Flags: needinfo?(arusso3)

Here is my screenshot after disabling webrender again.

And here I have drawn arrows at the visual artifact as it appears in your previous screenshot.

Do you notice the square edges that are being "cut out" of the drop-shadow on some of the text? The "R" also has a square corner sticking out of its front leg, same with the "h" letter's drop-shadow.

Hi @Anthony Russo, I've retested the issue with 2 different profiles on release 68.0.1 and latest nightly 70.0a1 but without success. I will attach both screenshots to see how it is displayed in my end.
Regards,
Liviu

Jessie, can you try to reproduce on the VR machine we have in the office.

Flags: needinfo?(jbonisteel)

Updated the VR machine to use the same driver. Still could not reproduce the issue.

Anthony - does this issue still happen for you? Does it happen with the latest version of Firefox?
