Fd leak with explicit sync and kde plasma

[gtschemer]

I am also experiencing this or a similar issue (on Bazzite 42), noting the sync_file count jumping every time I click on and off a KDE stacked application icon.

I also see semi-frequent KDE crashes with “Too many open files” in the log.

This is with Plasma 6.4.5, Qt 6.9.2, nVidia driver 580.95.05.
