--- Comment #30 from 399989567@qq.com --- (In reply to jubilantjerry from comment #27)
My guess is that the Ubuntu shortcut minimizes all windows attached to the main one, including tool windows, whereas the minimize button is actually just a normal button on the window that doesn't minimize the transparent part. Perhaps the restore logic doesn't explicitly restore the transparent window because Wechat / QQ / DingTalk expects the transparent window to always be present.
The system I use is Debian+X11, in wine7.18, in fact when I click the shrink button in the upper right corner of the window, the transparent window will shrink synchronously.
Sven, does your tool show whether windows are truly minimized or not? If so could you check if the transparent window is still there if you minimize DingTalk on Windows?
I think the tool can't do this. The tool is WinSpy.exe you can download on URL:http://www.catch22.net/assets/files/software/WinSpy17.zip
