I find myself unable to click links on occasion. I have to reload the page every once in a while.

[Scanorama]

I find myself unable to click links on occasion. I have to reload the page every once in a while.

I am especially experiencing this on Youtube where if I click on a video, it loads another video that is towards the top of the page. It's like as if the page loads, but the link didn't and remain stuck on top, if that makes sense.

It started happening with the 0913 nightly build.

I've seen both phenomena, too (links not being clickable at all, or, on pages with many links, clicking on one and having another one loaded), and since a few more days already.

I've also had it happen that when I tried to mark text in one place on a page, it actually marked text in a different spot somewhere else a few lines away, so to me it rather looks as if the handling of mouse coordinates is borked sometimes.

Possibly unrelated, but since a few days I'm also seeing parts of page content not being painted sometimes, or flickering when scrolling. Unfortunately, all this stuff is not reliably reproducable here, since a simple reload always fixes it.

Thanks, well explained... I too have seen all the above the past 2-3 days, very intermittent.

And here I thought it was just me missing the intended link by a couple of lines. I was trying to wrap up my tax preparation and several times the wrong document came up when I thought I had the mouse over the correct link.
