Calc mouse snapping: weird bug / feature?

so I started using LibreOffice recently, and I had this weird bug, where my mouse snapped to the top of the first line with the letters.
Video for more information

The snapping is only downwards, and happened only on one document(after I restarted Libre Office Calc it went away)

Which version of LibreOffice and did you try to disable OpenGL or Skia rendering (which one depends on the version of LibreOffice) in Tools -> Options -> View -> Graphics Output?

as I have stated, it started working after I restarted the program, so not sure what caused it in the first place.
my version is Version: (x64)
Build ID: a726b36747cf2001e06b58ad5db1aa3a9a1872d6
CPU threads: 6; OS: Windows 6.3 Build 9600; UI render: default; VCL: win;
Locale: en-US (en_US); UI-Language: en-US
Calc: CL

its more of a slight inconvenience than a long-lasting problem, just want the devs to be aware of it, if maybe it happens to more people.

just want the devs to be aware of it,

Then you are wrong here. This site is users trying to help other users with their questions related to LibreOffice usage. If you intend to make developers aware of a problem, please file a bug report at bugzilla

ahh sorry, and thanks, Ill be sure to do that.
