Works fine for me. Does systemsettings actually crash, i.e. does the crash reporter trigger? It is actually terminated by Xlib on XGetImage. Further investigation points to my UI font (HarmonyOS Sans), which is used on the first line of preview panel. With Noto Sans as UI font, it can open NotoSans-Regular.ttf, but not HarmonyOS_Sans_Regular.ttf (same error message). The HarmonyOS Sans font is available at https://developer.huawei.com/consumer/en/doc/design-guides-V1/font-0000001157868583-V1 Oh the link in my previous comment points to an outdated version, the current faulting version is at https://developer.huawei.com/images/download/next/HarmonyOS-Sans.zip Other Xft-based apps don't like this font either, resulting in same error messages and terminated. Seems like a bug in Xft. Impressive digging, thanks for creating that! Linking that URL in the Bugzilla field here and marking as upstream. |
