hotspot (no symbols)

Thanks!

So the log file doesn't seem to have anything suspicious -- the
registering/unregistering after remapping all finish in < 1s.

For the perf result, it seems that the top two hotspots (62.1% and 26.3%) are
symbols in libglib and libQt6Core. Would you be able to install debug symbols
for these, and use
https://github.com/KDAB/hotspot?tab=readme-ov-file#visualizing-data to see what
these are? If you could also go to the caller/callee tab and let us know what
is calling those that would be great.

I understand that getting debug symbols is rather complicated on gentoo, but
unfortunately those are needed so that we could figure out what is going on.
