CEF crashing on uploading file

[thefunkyjoint]

Ok, will do that and post the results here soon.

Just tested with the official CEF client and the crash happens.

I recorded a video :

https://easyupload.io/n5ixqu

Note that right after selecting the image file to upload, the client closes by itself.

That means that this might be an issue in the CEF library or that PC configuration has some incompatibility with Chromium.
I see that you posted this information in the CEF forum too and they will need the call stack of the crash.

Follow this guide to get the call stack :

Ok, i will do the steps to generate the call stack.

Actually the crash happens not only on this machine, it's a lot of other machines although not all.

After running the command from windbg, i'm getting this error ; any idea ? The file is on the correct path

The call stack needed to debug this issue appears when the EXE crashes and you click on the "View -> Call Stack" menu in WinDbg.

Then use the "Edit -> Copy Window Text To Clipboard" menu option to copy the call stack to the clipboard.

[thefunkyjoint]

The command i referred on the previous post (and the one i pasted the error log) is this :

.reload /f libcef.dll

I could not get the 'symbolized' call stack yet.

[salvadordf]

After that step you need to move the PDB file to the right directory inside c:\symbols\libcef.dll.pdb\
Then close WinDbg and open it again. Select cefclient in the “File->Open executable” menu option and press F5 to run cefclient.

At that point you need to reproduce the steps that cause this issue until cefclient crashes or freezes. Then select the "View -> Call Stack" menu option.

I tried to reproduce this issue in a different computer with an integrated Intel graphics card and everything worked correctly.

It's a tricky one... so far i have about 8 complains of customers, i entered some of them in Teamviewer and could reproduce the crash with the official CEF client after 102. Will keep searching.
