Regarding `frameless=True`

[AEBC08]

Sorry, my English is not good

I set frameless and transparent to True and used CSS style to draw rounded windows, but currently transparent is not supported on the Windows platform. After testing, I set transparent to False on Windows 11. Frameless windows have system default rounded corners, but systems below Windows 11 do not have system default rounded corners. I have also tried using win32gui to modify windows, but the results were not satisfactory. So, how can I draw a window with rounded corners on platforms below Windows 11?

Window transparency on Windows is an ongoing bug. The current implementation works on some platforms, but fails on others. Relevant discussion can be found here
