Supressing Valgrind SDL false positives (not working)

I’m running valgring to catch up some leaks. Right now, I have found only upstream leaks (PulseAudio/NVidia/X11)

valgrind_log.txt (6.7 KB)

That I tried to suppress using this suppression file

upstream_supp.txt (684 Bytes)

I have called valgring with this rc file

valgrindrc.txt (259 Bytes)

But leaks are still showing up. How can I suppress it?
