Comment 175 for bug 410407

I have a theory as to the cause. I'm experiencing this in Chromium with Compiz on, but I don't think it's the fault of either. When you hover over certain buttons/items in a flash box, they register as links with the OS, and the mouse changes to show that. For most cursors it changes to be a hand, on mine, the cursor just blinks, to each their own. However, when the cursor is in link mode over flash, and you click, the cursor is moved to the right by 1 pixel. I can verify that it's not just my mouse moving because it works on A) my trackball, and B) my touchpad, with my hands off the ball/pad respectively. Flash registers this click/move as a Drag, not a Click, and doesn't click the button. I can 99% guarantee this, because if I move my mouse to the left at JUST the right rate, the 1 pixel shift is counteracted, the click goes through as a click, and the button registers. This also explains the right-click trick, and very rapid click trick, as both of those register clicks before flash can shift the cursor. I'd like confirmation, from anyone with a low enough resolution monitor and a trackpad with separate buttons, to see the shift, and that it's only on links in flash.

I don't have a solution, other than get really good at clicking while dragging left at just the right speed.
