Off-by-one (pixel) bug about cairoshell HOT 7 OPEN

Which DPI scaling setting are you using on the 4k monitor?

from cairoshell.

DPI scaling is set to 175 on the 4k monitor.

Would you be willing to test a custom build to see if this is caused by what I suspect (incorrect rounding)? If so, do you need a 32bit, 64bit, or ARM64 build?

from cairoshell.

Here is a 64-bit build to try:
CairoSetup_64bit.zip

It would actually be much more convenient for me if you posted a diff so I could test with that.

I apologize for not getting back with you. I did look into the bug last weekend but when I opened the ManagedShell project I realized that I could fix all the little issues that annoyed me. I got distracted and added/removed a bunch of features for myself throughout the entire evening until bedtime.

I guess the most notable would be a 250ms delay to the Menu bar. It's nearly impossible to close/minimize a window without opening the menu bar. Took a different approach from how I think you would have implemented it. I added a new "MouseInitiatedAutoHide" property and a SetAutoHideStateFromMouse() setter function called from AppBarWindow_MouseEnter(). Then in the property-changed handler launched an asynchronous function to wait 250 milliseconds and check if the mouse is still located on the screen boundary.

Anyway, I'm yammering. Could you put up a diff?

Here are the ManagedShell changes: cairoshell/ManagedShell@master...metric-rounding
Here are the Cairo changes: master...remove-top-hack

Regarding what you mentioned adding a delay to the menu bar: This should already exist in Cairo; there is an "auto-hide show delay" setting in Cairo Settings > Advanced. Or am I misunderstanding the change?

As of #802, this should now be fixed.
