I have been using TeXMaths (0.48.2) for a couple of months with
LibreOffice (running under Linux Mint 19.3). I have been saving
the LibreOffice files in ODT format and inserting the LaTeX as SVG images.
Recently, I have found that the quality of some equations can be
best-described as "spidery". It seems to me that something changed in
LibreOffice for versions after 184.108.40.206. I have no problems with
LibreOffice 6.4.7 nor with 220.127.116.11. However, all version of 7.0.2, 7.0.3
and 7.0.4 exhibit the problem.
Interestingly, I see a similar problem when in LibreOffice I select
"About LibreOffice" from the "Help" menu. The text "The Document
Foundation" is spidery in all versions of LibreOffice where I have the
TeXMaths + SVG problem.
It seems unlikely that this is a problem with TeXMaths, but more likely
LibreOffice. However, I have seen no mention it on the LibreOffice forums.
I have included two images with this email, called good.jpg and bad.jpg,
that show the problem, both with some equations generated using TeXMaths
and the "About LibreOffice" menu window.
I would appreciate any thoughts you might have.
Steps to Reproduce:
1.Create SVG object and save and close file
2.Open file and view under LO <= 18.104.22.168 - fine
3.Open file and View under LO >= 22.214.171.124 - wrong
As in "steps to reproduce" above
Graphics should not be "spidery" in any versions of LO

ODT file exhibiting described problem
This file shows the problem with SVG images. Text in the file explains further.

images look good and the same in 6.4 => regression

The brand image tagline looks rasterized but isn't- the image is directly drawn from SVG without any further modifications. And it looks good to me on Linux.
However, the fancy about image became worse also on Linux too, and transparency and/or shadows are not respected anymore. So it's clearly an issue with the SVG filter.

Setting OS to "All" as https://bugs.documentfoundation.org//show_bug.cgi?id=139861 was set to dupe.
SVG display in LibreOffice on macOS is really wonky. Logo in About and StartCenter look blurry as do the icons when selecting SVG icon themes.
With the sample document, I bibisected the bug to the 7.0 backport of the following commit using repo bibisect-linux-64-7.0. This is the same as in bug 138684. I think there's a previous step to it, which isn't the same as in bug 138684, but I didn't bother looking for that (can, if it's important). Adding CC: to Mike Kaganski.

Don't apply transparency twice when drawing to mpAlphaVDev
Actually, this isn't an SVG filter issue.
