            Bug ID: 271201
           Summary: Ridiculous CPU consumption
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: php4fan at gmail.com

Steps to reproduce:

1. In Telegram Desktop, open any bot's webapp, for example open a chat with @DurgerKingBot and click "Order Food"
2. Check CPU consumption

With the DurgerKing webapp, the WebkitWebProcess process will consume about 30% CPU constantly, which is ridiculously high for such a stupidly simple html page with a few static images and nothing else.

With a webapp of mine which I can't share here, which was a similarly simple html page with a few dozens static images and one single very minimal css animation, CPU consumption was constantly around 260%.

TWO HUNDRED AND SIXTY PERCENT. (the exact same html page in Chrome consumes no noticeable CPU at all).
