My monitor is a standard 60 Hz display. AMD Software reports the actual refresh rate as 59.45 Hz, so I'm not using a 120/144 Hz display.@SooraMaru thanks for the details. For the artifacts: which game/screen was it, and does it flash for a single frame or stay for about a second? If you can, send /config/switch-frame-tap/log.txt and last.txt from the SD card right after it happens. For the smoothness: what refresh rate is your monitor? On 144 Hz 60 fps can look uneven.
@kingboxnt thanks, which homebrew app is it, and did you launch it from a forwarder on the home screen or from the album?
Regarding the artifacts, I've seen them in multiple games. In Pokémon Sword/Shield they often appear when opening/closing menus or during screen transitions. I've also seen artifacts in Smash, especially in moving/animated backgrounds.
I am attaching the log files and some brief evidence from Pokémon Sword.
