My Current Setup :-
While navigating the webpages (scenario as mentioned below). Only a white screen can be seen at times (randomly), but the same works correctly in Google Chrome.
Scenario:
(Below steps has been automated in the code attached)
1.Goto "http://www.incometax.gov.in/iec/foportal/"
2.click on login
3.click home tab
4.click again login
5.Stops at white screen.
Our Observations:
- CEF_VERSION = "91.1.6+g8a752eb+chromium-91.0.4472.77".
- CEF_Glue_VERSION : 91.1.6.0
- .NET_Framework : 4.0

5.Stops at white screen.
Our Observations:
- Error exists in older CEFglue-CEF Versions also.
- Tried Enabling/disabling Cache
- For the Final step,(ie error case), "OnLoadEnd" event does not fire, even though in the "OnLoadingStateChange" event "IsLoding" is False.
- When the Webpage is at a the white screen , right click Context menu is not seen when right clicked.
- The webpage mentioned above seems to be Angular web app , which uses many JS files and resources.
- Also, if we login using Our credentials( which i cannot share) , further pages (which use 200Mb of recourses) stop at white screen.
- Sample project to recreate the error is attached in this https://drive.google.com/drive/folders/1DmGpk7oJ5N8dbN9-u-OpAPNxmLhF40kn.
- Sample project is able to render webpages like Youtube.com and other resource intensive websites, without stopping at white screen.
- As per this link "https://magpcss.org/ceforum/viewtopic.php?f=6&t=18142", we increased the stack size to 2Mb , we get the same error.
