Thanks for replying.
This is actually not an error of Wine. It is because Kwin changed its configs.

Kwin introduced a new option in kscreen:

"Legacy Applications (X11)" scaling can be "Apply scaling themselves" or
"Scaled by the system".

If I choose "Scaled by the system", the windowed game runs fine.
If I choose "Apply scaling themselves" (which is the default one after kwin
upgrade), the Wine window becomes very small on 4K screen KWin Wayland.
