With trunk my application now gives lots of tracebacks when using
the main menu, which has some images set, though not using an
imagelist:
ERROR in LCL: TGtk2WidgetSet.CreateBitmapFromRawImage Incompatible

This is using GTK2. Has the implementation of the main menu changed
significantly? Unfortunately this is slightly tricky to debug, as
the entire desktop freezes.
Do you use Glyphs in the menu? Anyway, please create a bug report
and if possible, attach a sample project to reproduce. Thanks.
I do use glyphs on a few of the menu items. Unfortunately a small
project with just this doesn't show the error, so a sample project
will require some thought.
I assume it's a specific glyph that doesn't work. Try to add a DebugLn
with the menu item name into DRAWMENUITEMICON so that you'll know what
menu item and glyph causes it.

I have submitted https://bugs.freepascal.org/view.php?id=33099
It does not show the crash, but it does show some issues. My
investigations show that the test program does not crash in the same way
as Masked is false for the menu image, whereas it is true in my full
program, and I haven't been able to track down why yet.

Update: I found my main program had some code I had forgotten about that
explicitly sets transparent for each menu bitmap:
MenuItem2.Bitmap.Transparent := True;
and that is why the error is triggered in my main program. (The need to
do this may be a bug, but if so it has been present for a long time.)
