[X] I have searched both open/closed issues, no issue already exists.
CefSharp Version
124.3.50
Operating System
Windows 11
Architecture
x64
.Net Version
.Net 4.8
Implementation
WPF
Reproduction Steps
This happens only sometimes. I do not see any way to reproduce it.
Expected behavior
Browser displays PDF file's content.
Actual behavior
Browser shows a gray screen instead of file content.
E.g. this happened at 2024-05-21 16:37:32. But the cef-debug.log doesn't show any error except from some issue regarding an extension. I don't think this extension log message has anything to do with the issue described above as it is logged everytime you open a PDF file.
My first question would be, what I can do to investigate this any further. Can it be a concurrency issue? Is there another way to process the file instead of starting a Task in ProcessRequestAsync?
Is there an existing issue for this?

Does this problem also occur in the CEF Sample Application
No.
Other information
We're using CefSharp in a WPF
TabControl
to display PDF files which are located on a SMB share.The files are processed using a
ResourceHandler
implementation (see below).As this issue occurs only sometimes it may be some concurrency issue.
