У меня есть эта проблема: После создания этого окна откройте все вложенные расширители с правой стороны. (их 7). Последний содержит некоторые элементы. (TextBoxes) Попробуйте перетащить GridSplitter. Все в порядке, оно работает свободно. НО! Как только я нажимаю на один из текстовых полей (независимо от того, какой), перетаскивание становится безумным медленным (после того, как мышь иногда падает 3 секунды +). После нажатия на TextBox эти отладочные сообщения появляются на выходе:GridSplitter перемещается очень медленно
После этого безумного медленно увлекая происходит. В окне отладки во время паузы и перехода к следующему шагу отображаются эти сообщения:
'WpfApplication1.vshost.exe' (Managed): Loaded 'C:\Windows\assembly\GAC_MSIL\PresentationCore.resources\3.0.0.0_de_31bf3856ad364e35\PresentationCore.resources.dll'

Ну, я только что попробовал все возможные конфигурации, x86, x64 и Any CPU в режиме отладки/выпуска. Не изменилось. С каждым элементом управления, добавленным в блок, где находятся все те TextBox, он медленнее (с 3 вложенными scrollviewers ~ 25 секунд каждого перетаскивания) –
Я пробовал его на других машинах с теми же ОС и .NET-версиями/патчами, которые были установлены, и он действительно работает свободно ! Что, черт возьми, с моей установкой .NET (все машины были восстановлены с одного и того же изображения) –
хорошо .. я не могу переустановить установку. Это ключевой компонент победы 7, по-видимому. –
