Description coolo1mc 2018-09-10 02:27:32 UTC
Hair of most characters in overwatch has blocky artefacts on latest mesa-git (18.3) and llvm-svn (8)

This is using dxvk and wine-staging with sync and gallium nine patches.

Comment 2 coolo1mc 2018-09-10 11:59:20 UTC
to clarify, this also occurs on mesa 18.1.6 and llvm6
Comment 3 Thomas Crider 2018-09-11 11:09:45 UTC
can confirm, also happening on llvm 7 and mesa 18.3-git with vega 64
Comment 4 coolo1mc 2018-09-13 08:07:36 UTC
seems to be fixed on llvm 8.0.0svn_r342107-1 and mesa 18.3.0_devel.1.1a263b377c-1
overwatch also updated, not sure if thats related
Comment 5 Thomas Crider 2018-09-15 01:32:00 UTC
can confirm fixed on llvm8 for me as well. (still broken with current mesa git and llvm 7)

If you want llvm7 to work you might need to do a git bisect to see what fixed it and see if the fix can be backported to llvm 7 (assuming whoever fixed it isn't trying to get it included already).
