v55 performance issue

[pkhach]

updated:

CefSharp.WinForms.Example v55 scrolls large pages much slower than v51

To reproduce the issue open http://beggar-panda-58623.netlify.com in CefSharp.WinForms.Example v55 and v51 (32 bit) and try to scroll page.

A corresponding bug report was posted for CEF Sample Application, bit in C# version the problem is much more noticeable.

Win 7 and 10 (32 bit)

Thanks!

It looks like a Chromium bug. I have posted corresponding bug to the Chromium bug tracker: https://bugs.chromium.org/p/chromium/issues/detail?id=689373

Closing this now, as the problem reproduces in Chromium, will need to be fixed there.

The workarounds would appear to be

• Use the x64 build
• Rollback to a previous version
