Project SETI @ home has been around for more than a decade. It involves the use of free capacities of processors and video cards for the analysis of signals received in the framework of SETI. For this, special software is used that processes data from radio telescopes on thousands of computers around the world.
AMD is aware of the problem, but has not yet commented on this information and does not name the timeline for the release of the fix. For their part, the participants of SETI @ home on Reddit offer to temporarily ban the use of RX 5700 XT and RX 5700 cards.
Note that current AMD graphics cards are built on the RDNA architecture, unlike older models that were based on GCN.
