Describe the bug
When attempting to start an application that embeds CEF (https://github.com/obsproject/obs-browser) built with CEF 102 and newer on ARM64 Linux, only a black screen is rendered (eg: CEF 103 used https://github.com/Pi-Apps-Coders/files/releases/download/large-files/obs-studio-29.1.3-1-arm64-jammy.deb) . Not an issue on 101 and earlier versions (eg: CEF 98 used https://github.com/Pi-Apps-Coders/files/releases/download/large-files/obs-studio-29.1.3-2-arm64-jammy.deb) .

To Reproduce
Steps to reproduce the behavior:

  1. Download CEF ARM64 Linux 102 or newer from https://cef-builds.spotifycdn.com/index.html#linuxarm64
  2. Run with any test application
  3. See that the screen in black or not rendered

Expected behavior
CEF 102+ functions like it did on earlier versions.

Versions (please complete the following information):

  • OS: Ubuntu 22.04
  • CEF Version: 102+

Additional context
Does the problem reproduce with the cefclient or cefsimple sample application at the same version?
not tested currently with the sample application

Does the problem reproduce with Google Chrome at the same version?
no. all versions of chromium (102 - 116 tested) do not have this issue.

x86_64 builds on a system with mesa drivers (thats all I have to compare) don't have the issue at all

Thanks for the update. Based on your feedback this sounds like a system configuration or app-specific issue since it only reproduces with Linux ARM64 and the OBS application. Happy to reopen this issue if your debugging identifies a fix in CEF.

@WizardCM any thoughts on this CEF issue? I reported/documented in the discord https://discord.com/channels/348973006581923840/374636084883095554/1149548064160358450 and seemed to be a CEF issue since it only happens in 102+ yet here they don't want to classify as a CEF issue since it doesn't occur in the sample application.

Do you know of any significant differences between obs-browser and the sample application that would case one to show a black screen with logs as above and the other to work?
