I used Spy++ to check, and if my operation was correct, these are indeed
two separate windows.

You can also try running it on macOS with winemac.drv to check if it's

 This flickering only occurs when D3D12 hardware rendering is enabled.


I disabled vkd3d-proton’s d3d12.dll and d3d12core.dll, forcing Photoshop 23
into the software rendering process (CPU mode). The flickering during
dragging disappeared. Does this indicate that the window management is not
the issue?


After using spy++ to grab messages, I found that in cpu mode, there are
many different types of messages (WM_ERASEBKGND, WM_MOUSEMOV, WM_MOUSEDOWN,
WM_MOUSEUP, etc ) under the ps panel (the panel with the doraemon image),
but in gpu mode, there is only WM_NCHITTEST, why is this?

I feel that in gpu mode, the ps panel seems to be drawn with some kind of
canvas, and all the events, are taken over by some other mechanism, but I
don't clear what that mechanism is?
