Hello,   I have attached a project for re-production of my problem.   When Windows scale is set to something higher than 100%, compiled exe display main form visible behind login form while login form is displayed as "ShowModal" in main form's OnCreate() event. I have worse problems further in my production application like complete freezing of application in other forms.   However; - Delphi 10.2.3 generated EXE does not have that problem at all. - Delphi 10.3 exe does not have that problem (and any of other problems in my production application) if scaling set to 100% in Windows settings.   I would like if someone else can confirm that is actually a problem of Delphi 10.3 Rio.   I appreciate if anybody can suggest a solution/workaround.   Thanks & Regards, Ertan Delphi10.3_forms.zip
