GTK-3, can not stretch (narrow) forms

[linuxfan]

I am using GTK-3 (on debian stable) in order to use webkit-gtk.

Starting from Lazarus 3.0 (now I use 3.2) a strange thing happens: when running the program, the forms can not be made smaller than the last dimensions set in code (enlarging is possible). I mean: when I resize the form while designing, no problem. When I run the program, the form cannot be made smaller. If the program sets dimension during startup, no problem - but interactively is not possible to resize any form smaller than last set dimensions in designing/running code.

I checked the Constraints property, and all fields are set to zero.
I even tried to set MinWidth/Height to other small values (40), but nothing changes.

I don't know what else to check.

Do you have code in the OnResize event making changes?

[linuxfan]

No, no onresize handler

I think you need to prepare a minimum example that fails and present it to the bug site.

Thank you.

To see the problem, just create a new project; in project options set LCLWidgetType to gtk3, and run.

The form of the program opens, and it cannot be resized smaller than the designed one.

I'll see how to submit a bug but, in the meantime, it would be nice to understand something more about this.

Is anything happening in the onchangebounds event of form?

[linuxfan]

In my code there are no events... what should I do to trace what is happening?
