- Hyprland 0.57.2 is a maintenance release based on version 0.57.1.
- It stops acquiring real-time scheduling during initialization to address crashes under heavy system load.
- It fixes rendering artifacts involving overlapping floating windows and improves fullscreen handling.
- Window placement, special workspaces, keyboard modifiers and Lua window references receive fixes.
- Additional changes improve layer ordering, child-process handling and compositor shutdown.
A stability-focused maintenance release
Hyprland 0.57.2 is a maintenance update for the dynamic tiling Wayland compositor. Rather than introducing a new feature set, it concentrates on regressions and stability problems identified in the 0.57 series. It follows version 0.57.1 and brings another round of patches backported from the main development branch.
Fix for crashes under heavy system load
The most significant change addresses crashes associated with real-time (RT) scheduling. Hyprland no longer attempts to acquire real-time scheduling during initialization. The previous behavior was associated with crashes when the system was under heavy load; removing that scheduling request addresses this particular crash trigger.
Rendering artifacts and fullscreen behavior corrected
The release fixes rendering invalidation artifacts that could appear when two floating windows overlap. It also corrects fullscreen handling for certain applications. Another fix addresses the scrolling layout, which could fail to restore the previous column width after leaving fullscreen mode.
Window-management and workspace improvements
- Floating windows: Placement is now preserved relative to the parent window.
- Special workspaces: A bug preventing windows from being unpinned onto a special workspace has been fixed.
- Fullscreen layers: Background and bottom layers can now appear beneath fullscreen windows.
- Scrolling layout: The previous column width is restored correctly after leaving fullscreen mode.
Keyboard, Lua and Wayland protocol fixes
Keyboard modifier resolution has been corrected for remapped keys, helping customized keybindings behave as expected. For Lua-based configurations, the update fixes access to an expired window reference from a Lua object. It also improves nested surface ancestry handling in the Wayland subcompositor and corrects pointer-grab checks.
Other protocol changes adjust application activation-token handling when a serial is missing and improve behavior when nested surfaces are being torn down.
Additional fixes and cleanup
- Brightness and saturation calculations have been corrected.
- Child processes terminated by signals are handled and reported more appropriately.
prctl(2)is enabled only on Linux, avoiding platform-specific issues.- Fullscreen-list cleanup during compositor shutdown has been adjusted.
- Configuration value limits, overlay presentation accounting and pointer refocusing behavior have received fixes.
Should Hyprland users install version 0.57.2?
Users running the Hyprland 0.57 series should review this maintenance release, particularly if they have encountered heavy-load crashes, overlapping-window rendering artifacts, fullscreen layout problems or workspace issues.
Why this maintenance release matters
A desktop compositor sits at the center of the graphical session. Crashes, rendering glitches and inconsistent window behavior can disrupt the entire workflow. Hyprland 0.57.2 is a practical stability update that strengthens the reliability of the 0.57 release series without changing the compositor’s overall direction.
