Description of problem: Calling the function XcursorLibraryLoadCursor() in libXcursor.so.1 causes it to go into an infinite loop constantly calling XcursorScanTheme() and segfault. This affects Steam, KWrite, Konsole (or any other app that embeds it), the Cursors section of KDE system settings and some text fields in Dolphin. Version-Release number of selected component (if applicable): 1.2.0-7.fc36 How reproducible: Always on my system Steps to Reproduce: 1. Open an affected app 2. Click the text field and press any key (Konsole, KWrite) or wait (Steam, KDE settings) 3. Observe Actual results: Konsole, KWrite: text field freezes (can't write anything), the rest is usable but crashes after a few seconds Steam: doesn't launch All: gdb and drkonqi show thousands of XcursorScanTheme() calls in the backtrace. Expected results: Steam launches, text fields are usable and don't crash the app Additional info:
Figured out what might be the cause of this. There's a cyclical dependency between the icon themes `breeze` and `Papirus`. The fallback theme `default` inherits from `Adwaita` which in turn inherits from `Papirus`. This means any apps that use the default theme (or any other mentioned) will make XcursorScanTheme() go into infinite recursion and segfault.
Breeze doesn't explicitly inherit any theme, see https://invent.kde.org/plasma/breeze/-/blob/master/cursors/Breeze/Breeze/index.theme Adwaita supposedly inheriting Papirus sounds very wrong, and isn't the case for the Adwaita on my disk, which only inherits hicolor
