Screen tearing is used to reduce latency and/or jitter in games.

## Enabling tearing

To enable tearing:
 - Set `general:allow_tearing` to `true`. This is a "master toggle"
 - Add `env = WLR_DRM_NO_ATOMIC,1` to your Hyprland config. This disables the usage of a newer kernel DRM API that doesn't support tearing yet.
 - Add an `immediate` windowrule to your game of choice. This makes sure that Hyprland will tear it.

{{< hint type=note >}}
Please note that tearing will only be in effect when the game is in fullscreen and the only thing visible on the screen.

Example snippet:
```env
general {
    allow_tearing = true
}

env = WLR_DRM_NO_ATOMIC,1

windowrulev2 = immediate, class:^(cs2)$
```

{{< hint type=note >}}
`env = WLR_DRM_NO_ATOMIC,1` is not recommended. If your kernel ver is >= 6.8, you can remove it.

For kernels < 6.8, this env is required.

Check your kernel version with `uname -r`.

If you experience graphical issues, you may be out of luck. Tearing support is experimental.

See the likely culprits below.

## Common issues

### No tearing at all
Make sure your windowrules are matching and you have the master toggle enabled.

Also make sure nothing except for your game is showing on your monitor. No notifications, overlays, lockscreens,
bars, other windows, etc. (on a different monitor is fine)

### Apps that should tear, freeze
Almost definitely means your GPU driver does not support tearing, like e.g. Intel's.

Please _do not_ report issues if this is the culprit.

### Graphical artifacts (random colorful pixels, etc)
Likely issue with your graphics driver.

Please _do not_ report issues if this is the culprit. Unfortunately, it's most likely your GPU driver's fault.

Could be the below as well

### Other graphical issues 
or
### Hyprland instantly crashes on launch
Likely issue with `WLR_DRM_NO_ATOMIC`.

NO_ATOMIC forces the use of a legacy, less tested drm API.

Please _do not_ report issues if this is the culprit. Unfortunately, you will have to wait for the Linux kernel to support
tearing page flips on the atomic API.
