--- Comment #13 from Ilya Kurdyukov <jpegqs at gmail dot com> --- I'll try to create a test that demonstrates this problem. Right now, I have a very large test image, I'll try to find a smaller one that reproduces the issue. One more detail: I rewrote the RVV 1.0 code using RVV 0.7 intrinsics for xtheadvector. When I compile this code with -march=rv64gcv and run it on a device with RVV 1.0, there are no artifacts, and disabling RVV_PATH2 doesn't affect the result. However, there is a difference, that xtheadvector device has vlen=128, while RVV 1.0 device has vlen=256. But code should work correctly on vlen=128.
