After some playing with Lazarus under Mojave on several machines (with or without commandline tools for 1.3), I have noticed some additional strange behavior;

When compiling under Mojave, the application behaves strange at times. Controls do not get drawn or refreshed.

When compiling the exact same application under High Sierra, and then running it under Mojave, results in an application that functions correctly.

Since this is a little out of my league, I'm only guessing there may be an issue with the framework used by the compiler?

So far I have narrowed it down to a repaint issue.
Resizing for example the controls list in the object inspector, repaints the property list correctly. One does need to do this each time one does scroll.
The Messages Window is affected by this as well.
In Source Code window one sees this every now and then (for example when using the "Find declaration").

Also note that when switching to to Dark Theme, that none of the properties can be read (names become white on a white background, only the maroon "not default" values can be seen).

I did a little research and the origins of the issue are linked to 10.14:

Nice Find! Well, not so nice considering it causes issue ;-)

I noticed that indeed Refresh, Update, Invalidate, Repaint and Application.ProcessMessages most of the time do not trigger or help with the "repaint" of a control or form.

However ... when I compile my application under High Sierra and run it under Mojave, everything works fine (in contrast to compile and running it under Mojave).
