Can anyone else resize the panel of the directory picker (portal)?

Reproduction

When I invoke the directory-specific File Picker Portal (from Gittyup):

Demonstration

…I see the undermentioned:

^[1]

It’s fairly low quality, so the steps are:

Drag the divider, because the QFrame is too thin:

1279×580 59.5 KB
Whilst dragging, everything disappears:

1279×580 7.1 KB
When released, the buttons disappear:

1279×580 37.5 KB

All re-appears when the window is resized.

Question

Can anyone else reproduce this? I ask because it’ll help me ascertain whether to diagnose further or just file a report at BZ as-is.

For what it’s worth, I can’t get the “folder picker” dialog to behave like that - resizing the Places panel doesn’t seem to glitch out like in the video.

Does the same thing happen on your device on a fresh user profile?

rokejulianlockhart · April 22, 2025, 8:18pm

@johnandmegh, indeed, it doesn’t! I tried changing the font, and adding similar Places entries via Dolphin. Neither caused it to reproduce, even after a log out and back in.

Any idea of how to go about diagnosing this in my profile? I don’t know of a way to execute the Picker standalone, to see what it outputs to the terminal. I ask because I think this has occurred across a few installations, so I seem to be doing something that consistently induces it.

Hmm…it might be worth checking to see what differences exist between a working and non-working profile in either ~/.config/kdeglobals or in ~/.config/xdg-desktop-portal-kderc?

The former is where the actual splitter position is stored, and where some history items are stored - perhaps some directory name with special characters in the history causes that file to be parsed incorrectly?

rokejulianlockhart · April 25, 2025, 11:49pm

@johnandmegh, apologies for the wait:

Was trying to diagnose the filesystem being really slow, ^[1] all of a sudden, despite my hardware:
```
Processors: 12 × AMD Ryzen 5 7600X 6-Core Processor
Memory: 30.4 GiB of RAM
Graphics Processor 1: AMD Radeon RX 5700
Graphics Processor 2: AMD Radeon Graphics
Manufacturer: ASRock
Product Name: X670E Taichi
```
I was gonna provide a flamegraph, even though this was tangential, but gee, not even that worked, ^[2] even after overcoming KDAB/hotspot/issues/711#issue-3021222372.

In the end, just needed to reboot.
It also took me a while to realise that I’d need to use kwrite admin:///, since code can elevate to the superuser when necessary, but doesn’t do so when it’s merely attempting to access another user’s $HOME.

I don’t see anything of note in xdg-desktop-portal-kderc:

#!/usr/bin/env bash
sudo git diff --no-index /home/test/.config/xdg-desktop-portal-kderc $HOME/.config/xdg-desktop-portal-kderc

It could be kdeglobals’s’ History Items[$e] section by that reasoning, although it appears correctly escaped:
