Let's see what the viewport folks have to say for this one.
@Jeroen-Bakker @fclem This is another case where the
use_hq_normals_workaround = trueworkaround needs to be used. It popped up last week for a Radeon R6 (gcn2) as well (#95324). This gcn1 card, as well as an older one I have (firepro w2100), is similarly affected.Changed status from 'Needs Developer To Reproduce' to: 'Confirmed'
Yes agree! Both should be supported. And the HQ normals should be enabled automatically.
For people who suffer from this bug: Open a new blender file -> enable HQ in Performance settings -> File-Defaults-Save Startup File. Now a new blender file enable HQ automatically.
