Mesa has another patch that will be interesting for Linux gamers. This is actually a two-part fix as it was re-worked. The Witcher 2 [Steam, GOG] should have a lot less black flickering with this latest patch.
The first patch was here, but now Marek has re-worked a v2 of the patch here.
Checking on the bug entry for it, it seems it improves the situation greatly but is not a full fix, as Marek described:
QuoteThe remaining bug can be an instruction scheduling issue: v_interp is moved outside of the WQM or moved after the KILL opcode (which can break the WQM) or moved into a branch (same issue).
As always, great to see Mesa work progress and Marek is doing some really fantastic work for AMD GPU owners.
