Hyprland v0.57.1 releases with NVIDIA black screen fixes and keybind improvements

The Hyprland Wayland compositor has released version 0.57.1, a maintenance update that backports several fixes from the main development branch to the 0.57.0 series. This release specifically targets stability issues, including reported black screen occurrences on NVIDIA hardware and various input regressions.

In addition to hardware-specific fixes, the update addresses several protocol errors and configuration parsing bugs. These changes affect users relying on custom keybind chords, tablet input devices, and specific session-locking protocols within the Wayland ecosystem.

Technical improvements in Hyprland v0.57.1

• Graphics and Display: Resolves black screen issues on NVIDIA hardware and restores opt-in KMS dmabuf filtering; also improves monitor handling by setting max_bpc based on configured bitdepth.
• Input and Keybinds: Fixes exceptions during chord resolving for keybinds, prevents mouse event inputs from being shadowed, and adjusts value limits for tablet devices.
• Protocol Stability: Fixes a protocol error in session-lock caused by removed outputs and improves dmabuf protocol handling by refreshing format feedback after configuration updates.
• Rendering and State: Corrects surface rendering by drawing small surfaces at their logical size and fixes an integer underflow in workspace R parsing.

Why it matters

This update is significant for Linux desktop users running NVIDIA GPUs, as it addresses critical display failures. It also improves the reliability of the Hyprland compositor for power users utilizing complex keybind configurations and specialized input hardware like drawing tablets.
