Not a recent regression. I remember trying a build from last year, and I could still repro. Edit1 : The bug is reproducible with sw-wr as well.
Not a recent regression. I remember trying a build from last year, and I could still repro. Edit1 : The bug is reproducible with sw-wr as well. Edit2: I tested a build from 2020-06-23 and can still repro this bug (so its not a new regression). Then i tried an older build from 2019-06-23 which had Dx11 rendering enabled and couldnt repro. Then I force enabled WR, and could repro again. This implies that this particular testcase worked fine on D3d11, but has been broken on WR for years
