Description: 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 7.0.1.2. I have no problems with LibreOffice 6.4.7 nor with 7.0.1.2. 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 <= 7.0.1.2 - fine 3.Open file and View under LO >= 7.0.2.2 - wrong Actual Results: As in "steps to reproduce" above Expected Results: Graphics should not be "spidery" in any versions of LO Reproducible: Always User Profile Reset: Yes Additional Info: Version: 7.0.4.2 Build ID: dcf040e67528d9187c66b2379df5ea4407429775 CPU threads: 4; OS: Linux 5.4; UI render: default; VCL: gtk3 Locale: en-AU (en_AU.UTF-8); UI: en-US Calc: threaded

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).

Actually, this isn't an SVG filter issue.
