>>>>>the snap to a corner is working, although it still will miss it sometimes like it has been since 2018. Is there anyway to make the snap stronger to make it more accurate?

You can try to play with the settings of MOUSEMOVEELAPSEDTHRESHOLD System variable.

The default value for it is 25, you can increase it to 40 or more to have better OSNAP performance.
