I would like to help get this bug's status changed to confirmed. The following
is enough to cause the bug to manifest:
$ mkdir ~/test
$ touch ~/test/{000..999}.txt
$ kdialog --getsavefilename ~/test/
Observations:
1) This causes a slowdown of 22–29 seconds on my i7 + SSD laptop while kdialog
eats up 100% of a core. If you are not seeing the slowdown, you can of course
add a few nines ;)
2) Subsequent runs of the kdialog line are always slow.
3) The slowdown is always present, regardless of whether or not the "Show
Previews" button is pressed.
4) Toggling the "Show Previews" button after the dialog becomes responsive does
NOT cause any additional delay (this is not just because my example involves
only empty files—it happens in real directories, too).
5) I can also confirm that another aspect of the bug is still present: If we
instead run
$ kdialog --getsavefilename ~/
...THEN navigate to ~/test/ via the GUI, there is no slowdown whatsoever. I
feel that this is a key point because it shows that there is nothing inherently
slow about displaying a large number of files in kdialog.
Please take another look at this bug.
Arch Linux / Plasma 5.9.4 / Frameworks 5.32.0 / QT 5.8.0 / kdialog 1.0
