Hi @Sam_Devos! Welcome to the forums! I’m Francisco from Zwift Support.
Screen flickers and crashes can be super frustrating—even if they’re just for a few seconds, they can totally disrupt the vibe of a great ride.
For Windows users, there’s a patch out now that might help smooth things over. You can find more info on the Zwift Game & Companion App Versions.
Since you’re running an AMD Radeon RX 6650 XT, it’s worth checking that your graphics drivers are fully up to date or try to reinstall it manually. Outdated drivers are often the sneaky culprits behind flickering screens or random crashes, even if your PC seems to be running fine otherwise.
Give that a shot and let me know if it helps! If the issue crops up again, be sure to keep us in the loop on the thread Mike shared earlier. It’s also worth noting that this has popped up in-game version 1.86.0, released on March 18th, 2025—so we’re definitely keeping an eye on it.
