Unfortunately, this version is binary incompatible to 4.2.3 in some aspects. Chromium crashes when accessing some sites, e.g. https://www.xometry.com/ and push the quote button. Blender cannot export PNG files anymore.

Where did the discussion take place? Upstream does care about proper versioning. We should just nudge them.

Jan, Ismail, just FYI (given, you didn't noticed already).

As it turns out, the issue is related to a ffmpeg bug, introduced in 4.3 series:

https://trac.ffmpeg.org/ticket/8747

It might be appropriate to backport the fix to this package, since it might occur in many related operations. At least Blender 2.83.{2,3} is still affected. I'm going to apply the Blender Upstream fix for this issue right now:

Why does this package doesn't support smbclient on Leap 15.2/15.3?

I notice amf is not enabled. --enable-amf https://github.com/GPUOpen-LibrariesAndSDKs/AMF

Enabling AMF would allow Radeon users to have accelerated encoding, benefit also would allow obs to use accelerated encoding on opensuse.

Users would still need to have access to https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-45, but looking on https://wiki.archlinux.org/index.php/FFmpeg#AMD_AMF it is possible to install a small module, rather than the whole driver.
