--- Comment #5 from François Gouget fgouget@codeweavers.com --- Created attachment 70210 --> https://bugs.winehq.org/attachment.cgi?id=70210 Run test_instanced_draw() separately to avoid failures.
Further testing showed that: * Reproducing the failure is impossible if WINETEST_NO_MT_D3D=1. So this looks like a parallelism issue. * Reproducing the failure is still possible even if all the other tests are commented out except for test_il_append_aligned(). So the failure results from some bad interaction between these two tests.
So if we cannot find why test_il_append_aligned() and test_instanced_draw() cannot be run in parallel on cw-rx460, an option would be to run the latter after the other tests as is already done for test_stream_output_vs(). This is the purpose of the attached bug51181.diff patch.
