Setting CefSettings.background_color causes failed assert

[cloudshao]

Hey all,

When I try to set the background_color through CefSettings or CefBrowserSettings, I hit the following assert:

Code: Select all

[0411/145342.981449:FATAL:PaintLayer.cpp(2629)] Check failed: isAllowedToQueryCompositingState().
2017-04-11 14:53:43.035795+0800 cefsimple Helper[58112:18100000] GVA info: preferred scaler idx 0


Steps:

1. Clone cef-project
2. Go into the cefsimple project
2. In main, add:

Code: Select all

settings.background_color = CefColorSetARGB(255, 0x18, 0x18, 0x18);


3. Build and run

Repro rate: 100%

OS: Mac OSX 10.12.4
CEF: 3.2924.1570.g558741c, 3.2987.1601.gf035232
Compiler: Apple LLVM 8.0

Anyone know what's going on, or if there's a workaround?

Does it reproduce when using the Release build of the CEF libraries?

No, we don't hit the assert on Release build. Only on Debug.
