Comparison between Gwenview and Inkscape

SUMMARY
OBS Studio scalable icon (.svg) is rendered incorrectly as of Frameworks 6.23. The icon was displayed properly with Frameworks 6.22. Incorrect rendering affects KDE apps (including preview in Dolphin) and Application Launcher.

STEPS TO REPRODUCE
1. Install OBS Studio
2. Open Application Launcher and look at the icon (or open "/usr/share/icons/hicolor/scalable/apps/com.obsproject.Studio.svg" in Gwenview)

OBSERVED RESULT
Icon is displayed incorrectly - dark background is on top of circle.

EXPECTED RESULT
Icon rendered correctly - dark background is behind the circle and doesn't protrude.

SOFTWARE/OS VERSIONS
Linux: 6.19.0-1-cachyos-bore-lto
KDE Plasma Version: 6.5.5
KDE Frameworks Version: 6.23.0
Qt Version: 6.10.2

ADDITIONAL INFORMATION
I ruled out that the issue is caused by coincidental update of librsvg library (using bundled program "rsvg-convert" produced correct image).

On other machine (with Frameworks 6.22) scalable icon is also displayed incorrectly when opened in Gwenview. Updating to 6.23 caused this broken icon to be shown in Application Launcher (with 6.22 it was correct - perhaps it was a .png icon).
