WM_FONTCHANGE issue #1507

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

At app start, call the following code:

SendMessage (HWND_BROADCAST, WM_FONTCHANGE, 0, 0);

What is the expected output? What do you see instead?

CEF hangs. But if I kill the render process - CEF relaunches it and continues 
its execution normally.

What version of the product are you using? On what operating system?

CefClient (standard), v3.1750.1738
Windows 7 x64.

Again: the problem also reproduces on the standard cefclient from CEF3 
distribution.

Does the problem reproduce with newer CEF distributions (2171+)?

Yes (2171 x86).

I did not try but I'm sure x64 version is affected too.
