================================================================================ RETRO LCD 7-SEGMENT CLOCK - VERSION 41 RELEASE NOTES ================================================================================ Dear GNOME Extensions Reviewers, Thank you very much for taking your time to review this extension. Below is a comprehensive summary of the improvements and changes implemented in version 41. ================================================================================ IMPROVEMENTS AND FIXES ================================================================================ 1. SHADOW AND GLOW RENDERING OPTIMIZATION - Fixed shadow rendering issues in the "Retro LCD" (gray) theme where numbers appeared too dark and thick - Removed dynamic shadow updates from the clock refresh loop to prevent flickering effects - Implemented progressive shadow offsets based on glow intensity: * Shadow level 0: No shadow applied * Shadow levels 1-2: 2px offset * Shadow levels 3-4: 3px offset * Higher levels scale accordingly - Applied semi-dark gray shadow color (rgba(80, 80, 80, 0.6)) for better visual depth 2. STYLE CACHING AND PERFORMANCE IMPROVEMENT - Implemented intelligent style caching system to prevent unnecessary re-renders - Added _lastAppliedStyle variable to track previously applied styles - Style updates now only occur when actual configuration changes happen: * Font size changes * Clock color changes * Glow intensity adjustments * Display format modifications - Reduces CPU usage and improves overall extension responsiveness 3. RENDERING FIX FOR EMPTY DESKTOP - Resolved visual distortion when the clock is displayed on an empty desktop (wallpaper only, no open windows) - Added explicit z-index layering (z-index: 999999) to container - Implemented new stacking context with relative positioning - Applied opacity and shadow settings to ensure consistent rendering across different desktop states 4. ENHANCED ALARM FUNCTIONALITY - Improved alarm blinking state management - Integrated GStreamer audio support for alarm sounds - Alarm configuration properly resets style cache on activation/deactivation 5. MULTI-THEME COMPATIBILITY - Maintains proper glow effects for all themes (Neon Green, Amber, Retro Gray) - Each theme now has optimized rendering characteristics - Glow effects apply intelligently without affecting performance 6. CODE QUALITY IMPROVEMENTS - Better signal connection management through _signals tracking array - Comprehensive timeout cleanup to prevent memory leaks - Organized style reset procedures for view changes ================================================================================ TECHNICAL DETAILS ================================================================================ Supported GNOME Shell Versions: 45, 46, 47, 48 Bug Fixes: - Shadow flickering in certain numeric displays (particularly "7") - Incorrect shadow illumination in specific themes - Widget rendering inconsistency on empty desktop - Style recomputation optimization Performance Enhancements: - Reduced style calculations from per-tick to on-demand - Implemented memoization pattern for style strings - Optimized idle update handler for glow intensity changes ================================================================================ BACKWARD COMPATIBILITY ================================================================================ All changes in version 41 maintain full backward compatibility with existing user preferences and configurations. No user action is required to benefit from these improvements. ================================================================================ CLOSING REMARKS ================================================================================ This release represents significant improvements in visual quality, performance, and reliability. The extension now provides a smoother, more professional user experience while maintaining its retro aesthetic charm. We appreciate your thorough review and any feedback you may provide. Your attention to quality assurance helps us maintain high standards for the GNOME ecosystem. Thank you for your time and dedication. Best regards, Carlos Corral
