- Add pending_screenshots counter to WaylandLock
- Set pending_screenshots = output_count in locked() if screenshots enabled
- Timer skips rendering while pending_screenshots > 0
- Decrement pending_screenshots on Ready or Failed events
- When all screenshots done, timer starts rendering
- This ensures screenshots capture the desktop, not the lock UI
Fixes grey screenshot issue caused by capturing lock surface itself.
Matches swaylock-effects behavior: wait for screenshots before initial render.
- Timer callback: log each tick and commit status
- LockedSurface::update(): log background presence, fade alpha, feedback states
- Renderer::render(): log background drawing and fade alpha
- Ready event: log background set confirmation
These logs will help diagnose why screenshots are not displaying.
- Fixed brace mismatch and duplicate code in screenshot.rs
- Increased SHM pool size to 256MB for high-res displays
- Corrected wlr-screencopy protocol usage: send copy request in Buffer event
- Fixed background handling: set_background now updates LockedSurface.background
- Removed dummy background creation; screenshots set when ready
- Added format conversion for Xbgr8888 and Xrgb8888 to ARGB32
- Proper Y-inversion handling based on flags
The lock screen now displays captured screenshots as background.
Screenshots are taken immediately after lock, before UI is shown.
Matches swaylock-effects behavior: lock appears first, then screenshot
applies when ready (no blocking).
Fixes: black/red screen issues, screenshot not displaying.
