Hi,

I don't occur this behavior under Mageia6 KDE Plasma 5.

I attached screenshots of application with Qt5 and Qt4 widget set.

I think you must check your KDE Plasma 5 theme. Color of font of Label is the same as background color.

Are you using Qt or GTK components? Usually these types of problems are related to the GTK theme used by the KDE desktop so you should try to use another GTK theme in system settings.

He compiled program for Qt4 application on old OpenSUSE and Qt5 on newer OpenSUSE.

This is nothing to do with GTK+ theme.

Hi!

I checked and changed themes - nothing changes as result.

Hi!

No, I'm using Qt4 compiled Lazarus 1.0.14/fpc 2.6.2 on OpenSuse 43.2. I don't use GTK widgetset.

No, I changed Lazarus to 1.8, but I have many problems with code.
I need to adopt big amount of my code to the new version, because Lazarus 1.8 don't supports all components that I'm using.

OpenSuse 43.2 (KDE Plasma 5) + Lazarus 1.8 + Qt4 - don't has this (topic) problem.
