Vertical synchronization not working
Some weeks ago I start notice, that in Mozila Firefox all videos start have noticeable horizontal line. Later I found that this line appear always on any image ( not only video) when I scroll down any page. As I understand, something wrong with Vertical Synchronization on Mozila browser ( I dont have that problems when use other browser or watch video in video players). I don't have that problem when moving all Mozila window with mouse over windows desktop. I tried do some fixes that I found in internet, but it didn't help (set vertical synchroimpuls in nvidia control panel ).
Can anyone suggest, how I can fix that problem?
