I'm experiencing a strange issue with my second monitor. Whenever I drag windows to the corners of the second display, part of the window ends up displayed on my main monitor. It's pretty annoying! I've tried to pinpoint the problem, and I'm hoping someone can help me figure out how to fix this. I'll try to share a photo in the comments if necessary!

It sounds like you might be hitting a limit with certain apps, like Spotify, where they can't be resized below a certain width. Have you tried using a different program to see if it behaves the same way?
Check if your two displays have different zoom or DPI settings. That could be causing the misalignment when you drag windows around.
Yeah, they are set to different resolutions – one is 1080p and the other is 4K.
A quick workaround could be dragging the window so it partially goes off the edge of your second screen. It’s a dirty fix, but at least it shouldn’t show up on your main screen anymore. Just make sure to target the exact corner when moving your mouse.
You might need to manually resize your windows. Try dragging the right edge of the window to the left to see if that resolves the issue since double-clicking the title bar might not work with your current setup.

Actually, it seems to happen with all Windows, including Discord. I managed to fix part of it, but now the minimize and close buttons are cut off.
