Description Thiago Sueto 2021-02-20 12:21:33 UTC

SUMMARY
I use Ctrl+Alt+S to open System Settings more often than by clicking the launcher.
In recent updates however whenever I open System Settings by using my keyboard shortcut, the virtual keyboard (looks like Qt's) keeps glitching as if attempting to open itself continuously.
I have not configured anything to load the qtvirtualkeyboard.
This only happens with systemdboot enabled and with keyboard shortcuts.
It doesn't happen without systemdboot and it doesn't happen by clicking the launcher.

STEPS TO REPRODUCE
1. enable systemdboot
2. create keyboard shortcut to open systemsettings
3. open systemsettings via keyboard shortcut

Virtual keyboard trying to initialize.

I forgot to mention: seems to be happening only on Wayland, and it does not happen on every boot.

Comment 2 David Edmundson 2021-02-20 14:51:34 UTC

Well that's weird.

Can I have the result of both:

qdbus org.freedesktop.systemd1 /org/freedesktop/systemd1 org.freedesktop.systemd1.Manager.Environment


cat /proc/`pidof plasmashell`/environ | tr '\0' '\n'

I have manually set the following in my /etc/environment in the past:

QT_IM_MODULE=
GTK_USE_PORTAL=1
PLASMA_PRELOAD_POLICY=aggressive

And the only thing in my .bashrc:

export LIBVIRT_DEFAULT_URI="qemu:///system"

Comment 4 Aleix Pol 2021-02-20 23:48:29 UTC

Does refraining from defining QT_IM_MODULE address the issue?

This seems Qt trying to be overly smart and showing it, but all code using Qt's virtual keyboard was removed in 5.20 already. :S

Nope. And now I'm even more confused about this since it was removed in 5.20. :D

But I just did another round of tests and I figured the means to reproduce: bug 433293. It only happens whenever that one happens.

I also noticed that the virtual keyboard appears for a second whenever I click Dolphin's embedded terminal. If I have both System Settings' glitchy keyboard and Dolphin open and click the embedded terminal, it makes the glitch in System Settings disappear somehow as though it's summoning it for itself lol.

It doesn't happen with Konsole or Kate's embedded terminal.
