CEF Forum

Hi,
I am using CEF3 in my mfc application. I am facing following errors in logs:

Behavior: I am able to send the Post request but not able to render the html page.

I am launching CEF in using sub process and has set multi_threaded_message_loop as true. If I try to open another browser in the same application in the ongoing session, I am able to create a new browser and render the HTML page.
The above observation was on remote machine which did not have GPU.
If I try to run the MFC application on my laptop which has integrated GPU, I do not see this issue.
Do I need to pass some command line option or there is some other issue.

I really need help on this. Thanks in advance!

What CEF version? See the README.txt file for binaries that are required to support software rendering, and make sure that you are including them with your application.

CEf version is cef_binary_92.0.27+g274abcf+chromium-92.0.4515.159_windows32.tar
I have added following files in the bin dir along with my main executable:
D3DCompiler_43.dll*
cef.pak
cef_extensions.pak
chrome_100_percent.pak
chrome_200_percent.pak
chrome_elf.dll*
d3dcompiler_47.dll*
icudt.dll*
icudtl.dat
libEGL.dll*
libGLESv2.dll*
libcef.dll*
resources.pak
v8_context_snapshot.bin
CefSimple.exe(sub process to launch CEF).


My program earlier used to work. It is showing this weird behavior now. Is it somehow related to GPU or CPU consumption.

You also need the swiftshader directory. These files are required for software rendering when the GPU is absent or blacklisted.

I don't understand. I have already added libEGL.dll and libGLESv2.dll (which are present in swiftshader dir). Do I need to exclusively keep them in swiftshader dir.

There are two different versions of those files (inside and outside the swiftshader directory). You need both versions in the correct location.
