Youtube player moves to the left second after loading the page

[matejdro]

When page loads player will be in center like normal, but second after it will move to the left side (like on the pic). Interacting with player (playing, pausing) will move it back to the center. I thought it is caused by prevent autoplay at first, but disabling it does not fix the issue.

Running Firefox 37.0.2, Greasemonkey YC build 507, HTML5 player

Same behaviour here, jumps to the left after the website has loaded. Needs interaction to get it back to the center. Tried to reset the settings without success.

Same issue here on latest Chrome Stable.

I have a similar issue. When my video loads up (on the Fill size which is my default) it loads a couple inches to the right, and then interacting with the video fixes it.

I'm using build 509 Greasemonkey, and Firefox 37.0.2

I'll join the club. On 507 the player jumped to the left border and back (although no interaction was needed for it to fix itself). On 509 however it jumps only about 2 centimeters and realigns itself much more quickly.

Firefox 37.0.2

May have the same issue here. When I load up a YT video it jumps for one second or a little more and then to the correct position but without any interaction from mine.

Using the userscript version 538 and Waterfox but also had the issue with Firefox.

Sorry for posting late, but I have the same issue. However a little bit different from OP.

I have fill as the default view, when I open some videos (not all) the player is moved to the right, but when I play/interact with the player it returns to the center again.
