切换回应用时窗口闪屏问题

Type: Performance Issue

在最大化窗口下，通过 Alt+Tab 或点任务栏切换回 CodeBuddy 时，窗口会出现一次缩放/屏闪效果，仅 CodeBuddy 有此现象、其它程序正常、且在多台不同设备上均能复现。建议：①提供"关闭窗口焦点动画/重绘"的设置项；②排查 Native Window Occlusion 在切换焦点时的整窗重绘逻辑。

When switching back to CodeBuddy via Alt+Tab or clicking the taskbar in full-screen mode, a window scaling/screen flicker effect occurs. This phenomenon is exclusive to CodeBuddy, with no issues in other programs, and has been consistently reproduced across multiple different devices. Recommendations: ① Add a setting to "Disable window focus animation/redraw"; ② Investigate the full-window redraw logic of Native Window Occlusion during focus switching
