Description jeremy9856 2015-06-10 18:51:12 UTC 
SDDM login manager configuration window can be "unresponsive" when you want modify SDDM settings. The window display SDDM settings but you can't change them. The window is not "blocked" you can click on an other setting module that work.

Also, sometimes the SDDM window don't actualize and, for exemple, stay on an other setting module, like "Desktop Session" settings.

Reproducible: Sometimes

Steps to Reproduce:
1. Open SDDM login manager configuration

Actual Results:  
Window can be "unresponsive" but not "blocked"

Expected Results:  
Window behave normaly

I tested on the latest version available here ppa:kubuntu-ci/unstable (5.3.90) and it's still the same.

Thanks

Confirmed on 5.4.2.

(Besides that the default window size is too small or the controls too big so weird horizontal scroll bars appear)

A little reminder.

Same with ROSA packages (Plasma 5.5.2).

When run from systemsettings SDDM KCM is always unresponsive in my test VirtualBox machine. But when run just as "kcmshell5 sddm" it works fine.

That seem to be right.

I just tested, for fun, the Nouveau drivers and the windows don't seem to be unresponsive anymore !

Maybe it's a problem with the Nvidia drivers ?

But VirtualBox with 3D Acceleration turned off is also affected.
Comment 15 jeremy9856 2016-01-22 14:00:07 UTC 
Maybe it's a problem with some drivers ? Nvidia recently fixed their driver for a problem with Qt that impede KDE softs.
Comment 16 jeremy9856 2016-02-19 09:48:26 UTC 
Is there a fix planned ?
Comment 17 jeremy9856 2017-09-21 18:41:12 UTC 
Maybe that can be closed now. It doesn't seem to happen now.
