ارجو المساعده في البرنامج الحالي .......برنامج رسم

.
.
فكرة البرنامج عمل  مطر وثلج باستخدام  (  switch )  _لم يتم كتابتها  بعد_  لكن المشكله انه  عند ما قمت بعمل الدواره لصنع قطرات المطر 
تقوم بحذف الالوان الاخرى للاجسام التي تكون خلف القطرات
وعند عمل   دالة   cleardevice  يظهر وميض غريب  

اتمنى حل سواءً لمشكلة مسح الالوان او مشكلة مسح الوميض 

واذا كانت هناك اي تعديلات اخرى اتمنى ان لاتبخلوا علينا بها 
ولكم جزيل الشكر
