My scripts are mostly trying to do some background clicking using
PostMessage/SendMessage and window resizing/positioning using
MoveWindow. I used to be able to use SendMessage reliably before this
computer upgrade, but now it seems like I need a combination of
PostMessage + SendMessage to see a click at all). For MoveWindow, the
results are entirely unpredictable (window isn't moved at all, window
resized and moved to the wrong location, etc).
I assume this has to somehow be with my setup and not pywin32, but I
am lost on what might be causing this weird behavior. Any insight
would be greatly appreciated!
If you upgraded your display as well, the problem is probably the
display scaling. Unless you mark your application has being "high DPI
aware", Windows will lie to you about pixel locations. If your display
is 3840x2160, but you have scaling set to 200%, your "non-aware"
application will be told that the display is 1920x1080, and the pixel
coordinates you are sending to other applications will be wrong. Go
read about "high DPI aware" applications. It's a mess.
