That would be an interesting step. Another thing to try is to call the APIs to make your app "high-DPI aware". You can do that for one process using this code: ``` from ctypes import windll user32 = windll.user32 user32.SetProcessDPIAware() ``` Or you can use a registry hack: https://stackoverflow.com/questions/43401709/marking-your-python-program-as-high-dpi-aware-seamlessly-windows -- Tim Roberts,t...@probo.com Providenza & Boekelheide, Inc. ___ python-win32 mailing list python-win32@python.org https://mail.python.org/mailman/listinfo/python-win32

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.

[python-win32] Unpredictable behavior of pywin32 on new computer
Hello, I have recently upgraded my computer and after upgrading and installing pywin32, I have found the behavior to be extremely unpredictable and in a lot of cases, just wrong. Environment: Python 3.10 (upgraded from python 3.9 on the previous computer) pywin32 304 Windows 10: 19044.2006 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!
