Research direction

Reproduce the issue in the desktop app on Windows 10 using a small window and the title-bar or toolbar drag region. Trace the window-drag handling and pointer rendering involved in that interaction; done means the window follows the real pointer normally and no frozen second pointer remains.

Description

Summary

小屏状态下拖动窗口移动时，窗口会"失去控制"：

  1. 窗口不再跟随鼠标，而是朝拖动方向缓慢自行漂移；
  2. 屏幕上出现两个鼠标指针——一个"假指针"冻结在拖动时的位置不动，另一个真实指针随鼠标正常移动；
Area

Desktop app

Reproduction or evidence
  1. 使用小窗口；
  2. 在标题栏或工具条可拖区域按住鼠标拖动窗口；
  3. 观察：窗口脱离鼠标控制继续缓慢移动，且拖动起点处残留一个冻结的光标图像。
