Hello, does anyone else has experienced some problems in
ActionUpdate(), under the following conditions:
- Kde/Qt- Linux x86_64ActionUpdate event is constantly called:

Currently I'm forced to lock the method with a counter.
Additional precision:
the event is created from a Form from a TAction List.the problem does
not exist under WindowsLocker is a CPU-registry-wide data
(NativeInt).Code: [Select]TMyForm.Action Update(AAction: TBasicAction;
var Handled: Boolean)
Begin
  Handled := true;
  if Locker > 0 then exit;
  Inc(Locker)
  try
    //...updates: actionthis.enabled := true; actionthat.enabled :=
...; and so on
  finally
    Dec(Locker);
  end;
End;


Actually if I don't use this protection pattern, the application
completly locks for a while...
Has anyone else experienced the same ? LCL bug maybe ?
