高分屏界面里的图标显示粗糙；The icons on the high-resolution screen display roughly.

The version I'm using here is Windows 11, with the screen scaled to 125%. In this scenario, the icons on the interface of WindTerm 2.6 look very inconsistent, all jagged.

Reproduce the issue in WindTerm 2.6 on Windows 11 with display scaling set to 125%, using the attached screenshot as the visual reference. Trace which desktop UI icon assets or rendering path produces the jagged icons, then verify that the affected icons render cleanly at high-resolution scaling.
