System Information

OpenCV python version: 4.10.0
Operating System / Platform: MacOS Sonoma 14.2
Python version: 3.10

Detailed description

I have made a simple highgui functionality to keep/restore aspect ratio after changing the size of the Window.
It uses:

• cv2.getWindowImageRect(self.window_name)
• cv2.resizeWindow(self.window_name, width=nw, height=nh)

However even if it never changes and only calls cv2.getWindowImageRect the memory grows like 100MB every few seconds.
I did not experience it on Windows.

Steps to reproduce

Set up the window: cv2.namedWindow(self.window_name, cv2.WINDOW_NORMAL)
In reading image and processing loop:

            rect = cv2.getWindowImageRect(self.window_name)
            x, y, w, h = rect
            nh = int(round(w * self.aspect_ratio_yx))
            nw = int(round(nh / self.aspect_ratio_yx))

           window.show_image(image)
           key = cv2.waitKey(1)

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
• I updated to the latest OpenCV version and the issue is still there
• There is reproducer code and related data files (videos, images, onnx, etc)
