Update - Tooltip Flickering
We are aware of a new tooltip-related bug that can cause flickering.
Unlike the prior tooltip issue, which has been resolved, this bug does not cause the entire page to move. Instead the tooltip itself turns on and off while the page is unchanged.
This bug happens when a tooltip-spawning element is positioned along an edge of the screen so the tooltip has no space to pop in other than on top of that element. This causes the hover to end, at which point the cycle repeats.
Since the position the tooltip appears depends of multiple factors like screen dimensions and degree of zoom, you may not see this bug at all, or it may happen very consistently.
We've tested a few solutions to this bug, but these fixes merely introduce new edge cases.
If you are susceptible to flickering lights, please be cautious of tooltip-spawning elements (item and dragon icons) located near the left edge of your screen. In some cases it may be best to avoid pages containing those elements entirely for the moment.
This is currently our top priority and we will launch a fix as soon as a solution is found.
