main menu missing on opensuse15.6/KDE

<< < (2/3) > >>

MarkMLl:
Comparing the two screenshots, the KDE theme's different. The one that correctly shows the menu has the pane corners slightly rounded and well-formed grips on the ribbon (top-left), while the one without the menu has sharp corners and crude grips. If it's not a theme issue it could depend on the precise widget set being used by the IDE... I'm not sure where to find that.

You can select the widgetset on the Tools > Configure "Build Lazarus" dialog. You can view what's in use on the View > IDE Internals >  About IDE dialog.

My guess is that the IDE is built using GTK but running on KDE.

OK got it working. I had to resort to using the opensuse desktop theme and layout rather than the default breeze theme installed on the system.

thanks everyone for your pointers

I'm using Breeze with KDE on Debian 12 and it works. However even on Debian there's several choices, and it's entirely possible that some variant of Breeze is shot.

Updated: I've switched from Debian's customised Breeze to Breeze Twilight, which appears to have fixed various instabilities after powering up the monitor.

Ultimately, I continued to have problems irrespective of theme until I added a Radeon card so that I wasn't relying on the PC's onboard Intel video controller.

So it would appear that Qt- and possibly other environments- is using some X11 facility that is poorly implemented by some drivers.
