A Light & Elegant
Desktop Hardware Dashboard

V0.8.5 — Frosted-glass surfaces + a glass / flat switch

• Every background is now frosted glass: window body, title bar, all seven chart cards and the disk panel; each gauge also gains a glass lens so the ring no longer floats in space
• A uniform milky, light-transmitting surface: vertical tint gradient, milky diffusion from the top, a 1px gradient rim and a whisper of bottom depth — no visible grain and no local hotspots (no DWM acrylic, so it looks the same from Windows 7 to 11)
• Fixed horizontal banding: GDI+ gradients are quantised per scanline without dithering, so a 15-level span over 600 px produced a hard edge every 40 px. The gradient is now rasterised in-house with an 8x8 Bayer ordered dither (±0.5 LSB) — invisible, but the bands are gone; rasters are cached per size so each frame is a single blit
• The disk panel is now dark smoked glass with the model name and percentages in opaque pure white #FFFFFF
• The pin / close buttons became glass pills that turn red with a white inner rim and glow on hover, and switch the cursor to a hand; pressing deepens them further
• Cached backdrop: the window background is rendered once and blitted per frame, so the glass theme costs only ~1.5-2% of one core more than the flat one (4-4.5% without the cache)
• Settings → Effects → Surface style: a glass / flat switch with the active option highlighted; switching saves first and restarts automatically, and flat keeps the previous look exactly
• Layout, fonts and colour settings are untouched — only the surface material changes; strings added for all 9 languages

V0.8.4 — Faster startup, fresher data, lower CPU/memory, broader hardware support

• First frame 0.75s → 0.55s, first painted frame 0.93s → 0.66s: the context menu and tray icon are now built after the first frame, and font initialisation is de-duplicated
• Sampling rate 1.6/s → 3.2/s: the collect loop now sleeps only the remainder of its interval, and LHM refresh is scheduled by time instead of by loop count
• CPU load comes from the PDH % Processor Time counter (same source as Task Manager) so gauges follow the UI refresh rate
• CPU 15.7% → 10.3% of one core: LHM is limited to the CPU/GPU nodes (memory uses PDH, network uses NetworkInterface, disks use WMI) and adapter enumeration is cached for 3 s (measured ~70 ms per call)
• Working set 121 MB → 104 MB, private bytes 84 MB → 71 MB; a 160 s soak confirms no leak (GDI/handles flat, working set only GC sawtooth)
• Adaptive CPU temperature sampling (2.4 s when stable, back to 1.0 s on change); disk WMI enumeration 5 s → 15 s
• Broader platform support: three-level base-clock fallback (WMI → registry ~MHz → skip scaling), CPU name fallback via WMI, and null guards around every LHM collection — Intel / AMD / Hygon / Zhaoxin

V0.8.3 — CPU readout on MSR-locked machines + high-DPI / display-scaling support

• Fixed the CPU frequency readout not matching Task Manager: on hybrid parts (e.g. 13900K) idle P-cores park at 800 MHz, so the per-core average read far too low (2558 MHz measured while the CPU ran near 5 GHz), and MSR-locked laptops were pinned at the nominal clock. Both now use the same definition as Task Manager — % Processor Performance × nominal clock (measured 4976-5018 MHz), with LHM's per-core clocks demoted to a fallback
• Fixed CPU temperature stuck at 0 on the same machines: a literal 0 is no longer accepted as a reading (shows "--"), and a validated ACPI thermal-zone fallback runs only when LHM has no value at all (a zone that never changes is rejected as a firmware placeholder)
• High-DPI fix: font size was scaled by the display DPI twice, so on a 4K laptop the text was oversized and the graphics tiny (font/layout ratio 0.339 at 250% vs the correct 0.178). The font scale now uses logical units, and the widget reads the real DPI of the monitor it is on and re-lays out when that changes

V0.8.2 — Stability hardening + memory/CPU optimisation + wider hardware support

• Global exception guard: an error in any UI handler or timer no longer closes the app — it reports and keeps running
• Crashes are logged to %LOCALAPPDATA%\XMoni\XMoni.error.log (capped at 64 KB)
• Font ownership rebuilt: removes double-dispose and GDI handle leaks (renderers no longer dispose caller-owned fonts)
• Opening Settings repeatedly no longer leaks font handles; tray tooltip / debug window / disk panel fonts are now released
• No more per-frame GDI object creation in the render hot path; the layered Graphics is cached
• WMI disk enumeration moved off the UI thread — disk data refreshes in the background, removing stutter
• Sampling rate now follows the UI refresh rate; forced GC.Collect calls removed
• CPU temperature: values outside 5–120 °C are rejected (AMD SMU failure values no longer shown as temperature)
• CPU frequency: P-core average → all-core average → WMI → performance counter fallback chain; fixes value flicker
• Network speed: adapter reconnect / counter wrap can no longer produce negative values or spikes
• Fixed network up/down values "vanishing for a second": an invalid delta (adapter set changed, counter wrap) is no longer published as 0 — the last good reading is kept instead
• Fixed sampling throttle: LHM's CPU update reads many MSRs (~380 ms/call), so updating it every cycle capped the sampler at ~1.5 Hz and left a bad sample on screen for over a second; CPU and GPU are now updated on alternating cycles
• Fixed "takes 10+ seconds to show the UI / sometimes opens with no window": LHM's hardware enumeration (measured 3.2 s, longer with more GPUs/disks) was blocking the UI thread; it now runs on the collector thread — first frame 3.64s → 0.51s, window visible and painted 3.74s → 0.70s
• Fixed "opens but nothing is visible" caused by an off-screen saved position: the window is now validated against the current monitor layout and moved back into view
• Fixed multi-GPU machines showing only one GPU row (rows are rebuilt once the hardware tree is open)
• Fixed a lost MouseUp during drag leaving the UI permanently un-repainted (appeared frozen)
• Fixed the network gauge's coloured reading indicator disappearing entirely at a rate of 0 (a minimal tick is now drawn), plus a render-level fallback so the readout can never be blank
• Missing fonts fall back automatically; rounded-rect drawing is guarded against degenerate rectangles
• A missing or corrupted language file no longer prevents startup
