Annoying white static lines in my Edge browser

If these vertical lines are on the edges of the screen try going into Display Settings (right click your desktop to access)
Make sure your scaling percentage is a multiple of 10 (100%, 150%) and not in multiples of 5 such as 125%. You can click 'Custom Scaling" to experiment with different percentages but this is not advisable for the reasons it states. The options in the drop down menu should be compatible. I would imagine leaving it at the 100% recommended scaling would be the best idea.
This is a known cause of vertical lines in full screen mode on Edge

If that is not the solution and if there are no other solutions offered why not avoid the problem by using a browser (in your case Chrome) that does display correctly on the Facebook site.
