Broken GUI in KDE Plasma 5.26 (Debian Testing)

[Freeedim]

As said in the title, the GUI is totally broken.

It's been the case for a while actually, but it slipped off my mind.

None of the bottom buttons appear, but they can be (blindly) clicked. When clicked, their menu items get scrambled when the mouse pointer hovers over them. When clicking on an item that was not too much scrambled, the launched action is however the next item's action.

I am using an X server (not Wayland), Sirikali 1.5.0 (Compiled with Qt 5.15.6).

My window management information is:

Do you have any volumes set to automount at start up or do you start the app externally with a volume path already set to unlock?

[Freeedim]

I am not sure I understand well your question.

I just click on the app in KDE Plasma's application launcher menu.

I have a VeraCrypt partition volume that automounts at system startup through crypttab and cryptsetup. But Sirikali has no settings from me (no auto-mounts, no favorites etc.)

[mhogomchungu]

I have no idea its not working for you. SiriKali uses QWidget and does not customize them in any shape or form.

Have you enabled hidpi scalling in SiriKali settings?
Are you using a dark theme in SiriKali settings?
Are you using a scale factor with a value other than 1.0 in SiriKali settings?

[Freeedim]

I couldn't know as the GUI was too broken to see anything on the settings panel.

So I just apt purge'd SiriKali and reinstalled it to have the default settings. And it's exactly the same, no improvement.

I do have a dark theme in plasma, with the default 100% scale and no forced font DPI in Plasma settings. My Look-and-feel theme is QtCurves (but I tried with Adwaita, Breeze, Kvantum, and nothing changed).

I have no error message in the system logs when opening SiriKali.

[Freeedim]

Actually, Sirikali works well if I launch it with:
sudo sirikali
My root user does not have a dark theme, in case it matters.

However, when run as root, here is what happens:

• "Enable HiDPI scaling is enabled by default.
• If I uncheck it, close the app, re-open it with sudo sirikali and go to the settings panel, the checkbox will still be checked.

To get default SiriKali settings in your user account, do the following:-

1. Close SiriKali
2. Delete SiriKali folder located at $HOME/.config/SiriKali
3. Start SiriKali.

Thank you, it solved the problem. It seems the conf file has a few different entries now. For example there was EnableHighDpiScaling=true that does not exist any more and EnabledHighDpiScalingFactor=0.8 that is now set to 1.0.

[mhogomchungu]

I can reproduce the issue now when setting the scaling factor to 0.8.

I am glad we found the problem and the current default value does not have it
