How to stop horizontal screen tearing during sandstorms on RX 590?

Whenever a sandstorm hit on Arrakis, unsettling horizontal tearing lines appeared across my screen. I tried enabling Enhanced Sync in the driver panel, but it increased input lag by nearly 30ms, which was incredibly frustrating. I used the GamePP Peripheral Driver Conflict Detector to set redundant lighting services to manual and optimized PCIe power management. RTSS showed frame intervals converged to 10-15ms; GPU temperature stayed at 72-78℃ per AIDA64 and clocks held 1300-1500MHz per GPU-Z.
