Application written with Chromium Embedded Framework CEF seems to have performance issue/lag

[skygunner]

5.43.7
Windows 10 20H2

Application example:
WeChat for Windows. Can feel it is slower when running in Sandboxie, especially when typing in Chinese, the input IME will take a bit of time , about 0.5 to 1 second, to render and display its UI and candidates. But after the UI has displayed, it will not lag anymore.

Program wirtten in winform doesn't have this issue.
Inputting english letter doesn't have this issue (because this mode does not require the IME to render and display a candidate UI).

Maybe this is due to the resources/multi threading etc has been restricted ?

Hyper-V, Device Guard or secure boot are not in use, not enabled. But I have vmware workstation pro insatlled.

Possibly related? #69

I'm not sure if this is related to issue 69. However it is performance related.

Opening the file explorer is very slow in Windows 10 20H2 or 2004.
The issue I mentioned, might be another issue.
Why I say this is because program written in winform like QQ does not have this issue.

I'm not sure if this is related to issue 69. However it is performance related.

Seeing as #109 seems related to #69, it's very possible this one could be too I'd think.
#109 says "Chromium based browsers" aren't having the issue, but I wonder if he tried on anything other than Edge (which indeed seems to not have it, or have it less severely). Chrome on my machine causes the problem as well.
