Added

• Current CPU Frequency Display: Added real-time display of actual CPU frequency (not just the max limit)

  • New currentFrequency property in CpuController that reads from /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
  • Exposed via DBus as CurrentFrequency property
  • Displayed in main UI Status Card with highlight color for easy visibility
  • Updates every 2 seconds alongside other metrics
  • Shows the actual current running frequency of the CPU, useful for verifying throttling is working

• Auto-Protection Cooldown Timer: Added configurable cooldown to prevent rapid CPU limit toggling

  • When auto-protection applies CPU frequency limit due to high GPU power, it will wait a configurable amount of time before removing the limit
  • Prevents rapid on/off cycling when GPU power fluctuates around the threshold
  • Default cooldown: 5 seconds (configurable from 0-30 seconds)
  • Cooldown slider and spinbox in "CPU Frequency Limit" card
  • Setting cooldown to 0 disables the feature (immediate removal like before)
  • Cooldown only applies to automatically applied limits, manual limit removal is instant
  • Persisted in daemon settings at /etc/uncrash/uncrash.conf

Fixed

• Fixed AMD GPU fan speed display showing incorrect percentage instead of RPM
  • AMD GPUs now always display fan speed in RPM (e.g., "949 RPM" instead of "949%")
  • NVIDIA GPUs continue to display fan speed as percentage
  • Uses GPU vendor detection to determine correct display format
  • Fallback logic: values >= 1000 shown as RPM, otherwise as percentage

  • Displays side-by-side with "Current Status" card for easy monitoring
  • GPU Section: Vendor, model, temperature (color-coded), fan speed
  • CPU Section: Temperature (color-coded), fan speed
  • Motherboard Section: Temperature (color-coded)
  • Color-coded temperatures:
    • GPU: Green <70°C, Orange 70-80°C, Red >80°C
    • CPU: Green <75°C, Orange 75-85°C, Red >85°C
    • Motherboard: Green <50°C, Orange 50-60°C, Red >60°C
  • Thermometer and speedometer icons for visual clarity
  • Icons use opacity transitions to prevent UI jumping

• System Tray Icon: Application now runs in the system tray

  • Shows window on tray icon click
  • Hide to tray instead of closing when clicking window close button
  • Right-click context menu with "Show Uncrash" and "Quit" options
  • Custom CPU chip icon design with three states:
    • Green CPU: Normal operation (no CPU throttling)
    • Red CPU: CPU frequency limit active (throttling)
    • Gray CPU: Disconnected from daemon
  • Dynamic tooltip showing GPU power and CPU frequency
  • Updates in real-time when manual throttle buttons are clicked

• CPU Limit Status Tracking: Added cpuLimitApplied property throughout the application stack

  • CpuController now tracks actual CPU limit state (not just threshold exceeded)
  • Exposed via DBus as CpuLimitApplied property
  • Synced to GUI client via DaemonClient
  • Enables accurate status display for manual throttle actions

• Enhanced UI Status Display:

  • Main status card now shows CPU limit state instead of just threshold status
  • New "CPU Limit Status" row with APPLIED/Not Applied indicator
  • GPU Threshold shows "(EXCEEDED)" badge when threshold is exceeded
  • Color-coded status indicators (red for active, green for normal)

• Menu Bar: Added File menu with Quit action (Ctrl+Q keyboard shortcut)

Changed

• Window close button now hides to tray instead of quitting the application
• Tray icon and status indicators now accurately reflect CPU throttle state for both automatic and manual operations
• Application continues running in background when window is closed
• Improved UI Layout:
  • Status and Temperature cards positioned side-by-side (50/50 split) at top
  • Cards have matching heights for consistent appearance
  • "How It Works" card now expands to fill remaining vertical space
  • Removed unused resource files (uncrash-active.svg, uncrash-normal.svg, resources.qrc)
• CPU Frequency Slider Behavior: Adjusting the CPU frequency limit slider no longer immediately applies the limit
  • Slider now acts as a configuration setting rather than an immediate action
  • Limit is only applied when:
    • Auto Protection triggers (GPU power exceeds threshold)
    • User manually clicks "Apply Limit Now" button
    • A limit is already active and needs to be updated to the new frequency
  • Prevents unintentional system disruption when adjusting settings
• Periodic CPU Frequency Monitoring: CpuController now updates current CPU frequency every 2 seconds
  • Ensures "CPU Max Frequency" display always shows the actual current limit
  • Updates automatically when limits are applied or removed by any mechanism

Fixed

• Fixed QML TypeError exceptions when quitting the application
• Added null safety checks to all daemonClient property accesses using optional chaining (?.)
• Added nullish coalescing operators (??) to provide default values when daemonClient is null
• Added explicit null checks in all event handlers before calling daemonClient methods
• Fixed boolean type error in "Apply Limit Now" button enabled state during shutdown
• Tray icon now updates correctly when manual throttle buttons are clicked
• Status display accurately reflects whether CPU limit is actually applied
• Icon state is no longer confused between "threshold exceeded" and "limit applied"
• Fixed UI jumping when fan speed icons appear by using opacity instead of visibility
• Fixed card height calculation to prevent content from being cut off
• Fixed "CPU Max Frequency" displaying incorrect value when limit is applied
  • Now properly reflects the actual current CPU frequency limit from sysfs

Fixed

• Fixed Kirigami.Card layout issue where content was cut off on initial app launch
• Wrapped card ColumnLayouts in Item containers with proper implicitHeight/implicitWidth bindings
• Removed conflicting anchors.fill constraints that prevented proper size calculation
• Cards now properly calculate and display their full height based on content

Changed

• Increased default window height from 600px to 800px for better visibility
• Increased minimum window height from 400px to 700px to ensure all UI elements are visible

• Fixed CPU frequency control in systemd daemon by replacing interactive privilege escalation (pkexec/sudo) with direct sysfs file writes
