Windows in IDE 1.8 RC 4 not re-sizable

[ATweaker]

Dear All,
Even though I am already following this forum for some time, I only today registered myself to be able to post a question. I am not quite sure where to address my question, therefore I post it in the beginners section.
I am using 1.8 RC4 and my problem is that several windows are not re-sizable. As an example I have attached the project wizard, but it is also with the settings. This way it is quite difficult to work with Lazarus and that is a pity. My question therefore is where I can bring this issue forward so it can be fixed?

thanks in advance,
Arie

I assume you use Lazarus with Gtk2 [?]

Please test the 1_8_fixes branch, there are bug fixes regarding Gtk2 and application scaling. See http://wiki.freepascal.org/Lazarus_1.8_fixes_branch, SVN:

I am using the latest OpenSuSE Leap version 42.3, so I assume I am using GTK-3. Nevertheless I checked and I have both installed. Tomorrow I will check the links you provided me, thank you very much. I will get back with the results.

Cheers,
Arie

I replaced OpenSuSE Gnome with KDE, problem is completely gone. Apparently there is also scaling problem in GTK-3. Nevertheless I am now released from this problem.

Thanks for the tip!
