KDE error popup
DESCRIPTION
I'm not entirely sure what caused this to start happening, and I can't find
many reports of the same issue online. I recall OBS Studio beginning to have
issues like this months ago, but I believe screensharing had worked for a while
after then, but I may be misremembering as I rarely screenshare. I'm on Arch
Linux with a Ryzen 5 7500F CPU, Intel Arc B580 GPU, and 32GB DDR5 RAM. I'm
using the linux-cachyos package, but this has also happened when I built my own
kernel. Whenever I attempt to start a screenshare in Discord (installed with
Flatpak), add a screen capture in OBS Studio (installed with the obs-studio-git
package), etc., I will get errors such as the following:
OBS:
```

```
I have no issues with PipeWire in general - the audio playback and similar
features work fine. The only unique changes I can think of regarding PipeWire
are that I set some PipeWire settings in ~/.config/pipewire per the Arch Wiki
instructions (`default.clock.allowed-rates = [ 32000 44100 48000 88200 96000
192000 ]`, `resample.quality = 10`, etc.) and I use JamesDSP application, but I
believe this has occurred before I began using JamesDSP, and it wouldn't make
sense why JamesDSP would cause this anyway, especially as it seems to not have
been reported for anyone else.
As for Discord, sometimes it produces an error in journalctl and then does
nothing, while other times it just does nothing and doesn't produce any
relevant journalctl content. Currently, attempting to start a screenshare will
display the popup to start a screenshare, but then nothing happens after
selecting one. This is what the journalctl log looks like during this; I don't
know if the KSplash error is relevant, but the logs from Discord are very
common and happen no matter what I do in the app:

```
In some cases in Discord, an error dialogue or journalctl entry such as what is
shown in this screenshot would be created: https://ibb.co/TDxqP3bH (I don't
have the log from May 15th because my journalctl entries auto-deleted, I just
took the screenshot at the time to show someone else, but I still have recent
entries and the problem is happening the same way.) I don't know what causes it
to log an error rather than doing nothing. I've kept a copy of my entire
current journalctl and dmesg and could provide them if it'd be useful, but I
wouldn't upload them on the public issue tracker for privacy reasons.
Taking screenshots and screen recordings with the Spectacle application doesn't
encounter any issues at all.
STEPS TO REPRODUCE
1. ??? (Unknown what makes this start happening)
2. Open any app that lets you screenshare
3. Try to screenshare
OBSERVED RESULT
Nothing happens and an error may or may not be logged.
EXPECTED RESULT
A screenshare would start.
