CachyOS's chwd profiles drop a workaround that never applied to Pascal and Maxwell GPUs, while CachyOS-PKGBUILDS carries a forked mutter with tearing support.
mutter: fork with tearing merged CachyOS/CachyOS-PKGBUILDS
CachyOS-PKGBUILDS now builds mutter from a fork with tearing support merged, so the compositor CachyOS ships diverges from upstream mutter and tear-free-vs-tearing behavior is decided by the fork rather than by GNOME's release cadence. Anyone tracking upstream mutter, or reporting compositor bugs, should check against the fork before filing.
profiles: Remove RTD3 workaround for NVIDIA dGPUs CachyOS/chwd
Vasiliy Stelmachenok says the workaround is no longer needed, that he still sees D3Cold on his dGPU after roughly 10 seconds of inactivity without it, and notes it was never applicable to the 580xx profile because Maxwell and Pascal GPUs do not support RTD3 at all. He also points at the removal of NVreg_DynamicPowerManagement=0x02 from cachyos-settings as a possible related factor.
Handle xswap configuration CachyOS/CachyOS-Settings
ventureoo's change closes the xswap configuration issue in CachyOS-Settings, giving the settings package handling for xswap rather than leaving it to manual configuration. The same change landed as a commit under Stelmachenok's authorship.
faugus-launcher: update to 2.4.1 CachyOS/cachyos-aur-derived
faugus-launcher moves from 2.3.0 to 2.4.1, a minor-version jump, with checksums and .SRCINFO regenerated and no risk flags in the static diff scan.
shader-slang: update to 2026.18.3 CachyOS/cachyos-aur-derived
The long tail is routine: shader-slang to 2026.18.3, chatgpt-desktop-bin to 26.917.71314, and claude-code to 2.1.283, alongside the uptime bot's statuspage commits, with the USTC and Nanjing mirrors both answering 200.
