I did that. I added a print of the GDK geometry.

gdk geometry : 10,33,320,240
Warning: GDK_CONFIGURE: Designed form is misconfigured because of bad compositing manager (see issue #25473).
Warning: GDK_CONFIGURE: Fixing problem by setting current LCL values l=655,t=220,r=1152,b=461
WM=mutter (muffin)
gdk geometry : 10,33,320,240

At the following point I clicked the TLAbel button on the component palette,
and the form was again resized to something 'too small':

WM=mutter (muffin)
gdk geometry : 10,33,497,241
AddComponent TLabel Parent=ReportPropertiesForm:TReportPropertiesForm 38,140,0,0
Parent is 'ReportPropertiesForm:TReportPropertiesForm'
TObjectInspectorDlg.FillPersistentComboBox: Updating ComboBox with components
WM=mutter (muffin)
gdk geometry : 10,33,320,241
WM=mutter (muffin)
gdk geometry : 10,33,320,240

The X,Y are of course completely bogus.

After this, I disabled compositing in Mint, and the situation is slightly
better. Now the window doesn't resize so much any more, but it still
resizes.

So the "if Gtk2WidgetSet.compositeManagerRunning then" can be removed in fact.


Anything else I can do ? (except dumping linux mint, obviously...)
