Do you have Safari extensions installed? Does disabling them fix this? the bug occurs only occasionally disabling extensions, reloading the page and cleaning cache has no effect, in this broken state only a restart helps also i remember somewhat similar thing happened in PDF files (pages would stop to render), but not sure if it still happens and if it is caused by the same bug will report back when i'm able to trigger it again thanks Created attachment 441534 [details]

Search bar overlay when bug is triggered
when the bug occurs, search bar overlay stays within viewport
When this happens, can you find the PID of the WebProcess for that tab in Activity Monitor, and then run 'sample <pid>' and attach the output? Created attachment 442261 [details]
