To elaborate a bit more about https://gitlab.winehq.org/wine/wine/-/commit/786d9d1685ac220081b10cc779d4d33... issue, its negative effect looks broader than the mentioned specific game behaviour. The fact the child windows are not clipped hints us nothing really about the possibility to bypass "offscreening" of parent's window client window. The most basic and common way to draw on a window which has an unclipped child is to draw parent (e. g., on WM_PAINT) and then update child on WM_PAINT it will receive after. Bypassing offscreening of the parent won't allow child image to appear regardless of whether it is used Vulkan or gdi rendering.
