Please describe the problem:
Hello,
today I tried to adjust the width of Genre column at Radio tab and when I try to do that (i.e point to a "|", hold down the button and move left) it behaves not correctly. Basically it "jump" a bit to the right and then it starts working, but it is like 4cm behind the mouse cursor. I just noticed I get this behavior in all tabs (Play queue,Library,Podcasts,...)

Steps to reproduce:
1. point a mouse to "|"
2. hold down the mouse
3. move left to make the column wider


Actual results:
it jumps (offset) of the mouse to the right (it narrows) and then it starts to grow wider (as expected) 

Expected results:
"|" stay bellow the mouse pointer and column will get as wide as I move the mouse

Does this happen every time?
yes

Other information:
no, thank you for nice software
