SUMMARY When I open a single file in a directory with many files, Gwenview freezes in several seconds. The reason seems to be that Gwenview insists on reading (meta?) info of every file in the directory. This is very annoying when opening a single image on a remote share (eg. mounted via sshfs or cifs), since startup may be delayed for more than a minute. STEPS TO REPRODUCE 1. Open an image with Gwenview in a directory with many files (thousands) 2. Image shows fully or partly, and Gwenview is frozen. Eg cannot go to next image in folder 3. Wait for a certain time, and Gwenview functions normally again. OBSERVED RESULT I did a strace in a folder pointing to a remotely connected filesystem containing ca 12000 jpeg files: $ strace gwenview file_2019_09_20_12_00_03.jpg Gwenview then spits out thousands of lines: stat("/home/user/mnt/host/share/file_2019_01_15_06_00_00.jpg", {st_mode=S_IFREG|0755, st_size=231511, ...}) = 0 openat(AT_FDCWD, "/home/user/mnt/host/share/file_2019_01_15_06_00_00.jpg", O_RDONLY|O_CLOEXEC) = 26 statx(26, "", AT_STATX_SYNC_AS_STAT|AT_EMPTY_PATH, STATX_ALL, {stx_mask=STATX_BASIC_STATS, stx_attributes=0, stx_mode=S_IFREG|0755, stx_size=231511, ...}) = 0 close(26) = 0 statx(AT_FDCWD, "/home/user/mnt/host/share/file_2019_01_15_06_30_01.jpg", AT_STATX_SYNC_AS_STAT, STATX_ALL, {stx_mask=STATX_BASIC_STATS, stx_attributes=0, stx_mode=S_IFREG|0755, stx_size=231348, ...}) = 0 EXPECTED RESULT Gwenview should show the single image, maybe start caching "next" and "previous" image in a background thread, not freeze.
