Everything looks good with a new build of cef and this applied.

I'm curious, what's the issue when the CEF build has use_gtk=true with this revert/change?

Qt by default relies on Glib for its event loop, which completely goes wrong with the GTK inside CEF (e.g. obsproject/obs-studio#7146).

We also normally should not need use_gtk or use_qt being enabled in our usecase, since both can lead to side effects.

@tytan652 Thanks! I hadn't noticed that since browser panels don't work on Wayland anyway. Is the GN define list used for OBS CEF builds viewable somewhere?

I can give it to you, note that we enable H264 decoding in ours.

For the latest CEF 6533, I used GN_DEFINES="is_official_build=true use_sysroot=true use_partition_alloc_as_malloc=false symbol_level=1 is_cfi=false use_thin_lto=false proprietary_codecs=true ffmpeg_branding=Chrome chrome_pgo_phase=0 use_gtk=false" and note that we use the sysroot.

Thanks! Looks like the only relevant override there is use_gtk=false, everything else is already handled similarly at some other level in CEF/Fedora packaging.
