Some characters are missing when using a keyboard event.

Postby senya » Wed Dec 29, 2021 3:01 am

Hello.

I have a problem with 'CefBrowserHost::SendKeyEvent', type = KEYEVENT_CHAR.

Sometimes some characters are not entered into the input line in the browser. It's as if the dispatched event disappeared somewhere.

The events 'CefKeyboardHandler::OnPreKeyEvent' for the entered characters are triggered correctly, which means that the disappearance occurs later.

System information.
cef_binary_79.1.38+gecefb59+chromium-79.0.3945.130_linux64
CEF Version: 79.1.38+gecefb59
Chromium Version: 79.0.3945.130
OS: Lubuntu 20.04 (64 bit)

I can't figure out why this is happening.
Maybe someone faced such a problem?
Thank you.

After some testing, I saw that this is 99% likely due to the use of proxy servers.

Maybe there is another way to solve this problem without stopping using proxy servers?

After some tests, I saw that disabling the proxy does not completely help with the disappearance of letters.
The input takes place in the search bar, and there are some special, interactive letters.
