Hello Marek,
this was time and nerve consuming (with all the LLVM 11
revert/re-revert).
FreeCAD vbo rendering bugs.
Mesa-20.1-rc4 is fine (sure)
Mesa git with #2840bc3065b reverted (glthread_draw.c deleted), too.
/opt/mesa> git bisect bad
2840bc3065b9e991b2c5880a2ee02e2458a758c4 is the first bad commit
commit 2840bc3065b9e991b2c5880a2ee02e2458a758c4

glthread: upload non-VBO vertices and indices for non-Indirect
non-IBM draws
This is basically the same thing u_vbuf does.
