Excessive CPU usage (and extreme delays, upwards of 30 seconds at times, waiting for "Save As" dialog to appear) in xdg-desktop-portal-gnome when saving a file from Chrome. Destination folder has 2722 files in it (issue seems to begin appearing at a few hundreds of files), on btrfs. Even once you've saved the file and the dialog is gone, 100% single-threaded CPU usage can continue for several minutes(!), and attempting to save another file during this time will lead to Chrome darkening the screen and then... sitting there not responding to keyboard input (but responding to mouse input) until the Save As dialog finally shows up again (again upwards of 30 seconds at times). Saving from Firefox has absolutely no issues. I don't know if it also uses xdg-desktop-portal-gnome or not. This is incredibly reproducible on my side and occurs every time I download more than "a few" files in succession. The more files I download, the longer it takes to do each one, even if I wait quite some time between each one. Effectively the only CPU usage is from xdg-desktop-portal-gnome (the other 5 cores are usually ~20% background load). strace after my CPU fan had already been maxed out for about 30s-1m the latest time: strace: Process 24504 attached mprotect(0x7f3b22a25000, 8192, PROT_READ|PROT_WRITE) = 0 mprotect(0x7f3b22a27000, 32768, PROT_READ|PROT_WRITE) = 0 write(17, "\1\0\0\0\0\0\0\0", 8) = 8 futex(0x556a26c2b860, FUTEX_WAKE_PRIVATE, 1) = 1 write(17, "\1\0\0\0\0\0\0\0", 8) = 8 recvmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\20\0\373b\347\1\0\0\224\240@\0\234\377\234\377\1\0\1\0\0\0\1\0\0\0\0\0\0\0\0\0"..., iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 1056 recvmsg(3, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(21, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\20\0\34\2\347\1\0\0\224\240@\0\234\377\234\377\1\0\1\0\0\0\1\0\0\0\0\0\0\0\0\0"..., iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 1056 recvmsg(21, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(21, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=3, events=POLLIN}, {fd=9, events=POLLIN}, {fd=21, events=POLLIN}], 3, 0) = 1 ([{fd=9, revents=POLLIN}]) read(9, "\31\7\0\0\0\0\0\0", 16) = 8 recvmsg(3, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(21, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(21, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable) openat(AT_FDCWD, "/home/jrunyon/.local/share/recently-used.xbel", O_RDONLY) = 29 newfstatat(29, "", {st_mode=S_IFREG|0600, st_size=561840, ...}, AT_EMPTY_PATH) = 0 brk(0x556a50516000) = 0x556a50516000 read(29, "<?xml version=\"1.0\" encoding=\"UT"..., 561840) = 561840 close(29) = 0 mprotect(0x7f3b2de16000, 24576, PROT_READ|PROT_WRITE) = 0 ... sat here for quite a while, then CPU fan spins down and it starts flooding the terminal ... eventfd2(0, EFD_CLOEXEC|EFD_NONBLOCK) = 29 write(17, "\1\0\0\0\0\0\0\0", 8) = 8 poll([{fd=29, events=POLLIN}], 1, 25000) = 1 ([{fd=29, revents=POLLIN}]) read(29, "\1\0\0\0\0\0\0\0", 16) = 8 write(29, "\1\0\0\0\0\0\0\0", 8) = 8 futex(0x556a4f2d5a10, FUTEX_WAKE_PRIVATE, 2147483647) = 0 close(29) = 0 openat(AT_FDCWD, "/usr/share/applications/org.gnome.Terminal.desktop", O_RDONLY) = 29 newfstatat(29, "", {st_mode=S_IFREG|0644, st_size=499, ...}, AT_EMPTY_PATH) = 0 read(29, "[Desktop Entry]\nName=Terminal\nCo"..., 4096) = 499 read(29, "", 4096) = 0 close(29) = 0 access("/usr/local/sbin/gnome-terminal", X_OK) = -1 ENOENT (No such file or directory) ... etc, appears to be functioning normally again, and goes through accessing a metric crapton of files ... I believe, but am not sure, that I had the same issue with -42.3 (which is the only other version of this package I've had installed). To make matters worse, if I kill the misbehaving xdg-desktop-portal-gnome, Chrome simply refuses to let me download files (and thinks that it has a download in-progress, warning me upon exit) until I reboot.
for posterity's sake, it would probably be good to include emerge --info in a comment
