JoKalliauer raised the priority of T40010: RFC: Re-evaluate librsvg as SVG renderer on Wikimedia wikis from Low to High.
According to https://www.mediawiki.org/wiki/User:JoKalliauer/phab/wikimedia-svg-rendering#table I think this task might be the most important one of Wikimedia-SVG-rendering . Almost all bugs reported in Wikimedia-SVG-rendering depend in the renderer.

JoKalliauer closed T307335: Png rendering of svg upload is missing the included <use> elements as Invalid.
@Qaz_Janssen You are using SVG2.0-draft. The current released Standard is SVG1.1.
Therefore the rendering of c-librsvg2.40 is strictly speaking correct, and your SVG is broken. (Most Browsers and the current rust-librsvg2.54 will render it according to SVG2.0, which is not released.)

JoKalliauer added a comment to T304050: Recently uploaded files without thumbnails in Commons categories.
@Draceane Sorry, that's true. The problem is that MediaWiki starts to processes images imho only on request. If you are the first requesting an image with the size 120px, MediaWiki starts processing the image. Some images might finish in time, however processing multiple images at the same time will lead to a holding stack, therefore some images are not finished.
JoKalliauer triaged T304050: Recently uploaded files without thumbnails in Commons categories as Lowest priority.
@Aklapper The screenshot might be from https://commons.wikimedia.org/wiki/Category:Snow-covered_roofs_in_Czechia or similar.

JoKalliauer renamed T304190: rendering of SVG fails after image without `width` and `height`, however it should render the svg-elements after the PNG-image from PNG thumbnails of SVG file with embedded "data:image/png;base64" not displayed correctly to rendering of SVG fails after image without `width` and `height`, however it should render the svg-elements after the PNG-image.
JoKalliauer added a comment to T304190: rendering of SVG fails after image without `width` and `height`, however it should render the svg-elements after the PNG-image.
An <image -element without width=" and height=" is an undefined behaviour in SVG1.1. For SVG2.0 it is defined at https://www.w3.org/TR/SVG2/geometry.html#Sizing. Since SVG2.0 is not released, the not rendering of images is imho correct. However even if images without width=" and height=" are not allowed/defined, the rest of the SVG-elements should be rendered, that's imho the bug.

@Yisibl The better is the enemy of good. Thanks for that comment, however skr-canvas is "This project is in pre-release stage. And there may some bugs existed.". I don't see any benchmarks. resvg had a optional skia-backend-support in earlier versions, but @RazrFalcon dropped it, so I'm doubtfull that is on a comparable development level as resvg.
