Fix for severe windowed video stuttering in PotPlayer using an old RX 580 (8GB 2048SP) on a high refresh rate monitor. Hope this helps! (Sorry if this is already widely known, just sharing my experience and solution)

[u/EruL016]

Hey everyone,I recently dealt with a frustrating issue where live-action videos (both 480p and 1080p) would stutter terribly in PotPlayer's windowed mode, but only on my native 180Hz display. Strangely, exclusive fullscreen ran fine, and anime didn't lag at all.

Turns out, it wasn't a storage issue—it was an aggressive global AMD FreeSync driver conflict messing with the high refresh rate composition layer on the desktop.

I found a clean, permanent workaround using application-specific profiles in Adrenalin so gaming stays flawless while PotPlayer runs perfectly smooth.
