    Hello everyone, I am using qt 5.12.2 with msvc 2017, I use qwebengineview class to visualize my website. But qtwebengineprocessd.exe uses 100% cpu while I run my project. And it loads my website very slow. How to resolve that? Can you help me? Thanks in advance.

      Hi,

      The usual recommendation: use a more recent version of Qt. The 5.12 series is very old and you should at least move to 5.15 if not Qt 6.

            @SGaist I have tried with qt 6 msvc 2019 but my website was slow again. Then I run my project in release mode. And it was all ok.
