### Flickering in XWayland games
|

|
||||
XWayland games may flicker or present frames out-of-order in a way which makes them unplayable.
|
||||
This is due to the lack of explicit synchronization in older versions of the proprietary driver.

This is due to the lack of implicit synchronization in the driver, and/or flaky explicit sync support

2. If your GPU is no longer supported by the 555 driver, install older Nvidia drivers which do not exhibit this issue. The
|

last ones which would work will be the 535xx series of drivers. These

can be installed on Arch via [these AUR packages](https://aur.archlinux.org/packages?O=0&K=535xx)

More info about explicit sync is available

[on this blog](https://planet.kde.org/xavers-blog-2024-04-05-explicit-sync/).
|
||||
3. Try disabling explicit sync. In some select cases, explicit sync may actually cause issues due to the flaky nature of Nvidia drivers.
|
||||
Set `render:explicit_sync = 0` in your hyprland config.
