Yes, it works! I applied the patch to kernel-4.16.0-0.rc3.git2.1. After
launching supertuxkart i see only:

[   22.471837] fuse init (API version 7.26)
[   52.346467] nouveau 0000:03:00.0: imem: OOM: 00100000 00001000 -28
[   52.346516] nouveau 0000:03:00.0: imem: OOM: 00100000 00001000 -28
[  108.372556] perf: interrupt took too long (2530 > 2500), lowering
kernel.perf_event_max_sample_rate to 79000


No artefacts.
