Karşılaştığın bu kayma sorunu mobil ve masaüstü arayüz tasarımlarında en sık yaşanılan sorunlardan biridir. Tam ekran ile pencereli mod arasında geçiş yaptığında formun boyutlarında da değişme meydana geliyor. butonlar da position.x ve position.y değerleri ilk hesaplandığı yerde alıyor
çözüm için kapsayıcı panel mantığını kullanmak daha sağlıklı olur
