PlasmaZones 2.3.15

4 changes, released March 21, 2026.

Shader preview crash on hover (#235): Moving the mouse over the shader preview in the editor dialog crashed with SIGSEGV in QV4::Lookup::getterQObject. The MouseArea.onPositionChanged handler’s QObject-backed event parameter was invalidated mid-evaluation by cascading signal chains on Qt 6.10. Replaced MouseArea with HoverHandler which uses a value-type point property.
CAVA settings not applied dynamically: Enabling/disabling CAVA audio visualizer or changing bar count/sample rate in KCM required a daemon restart. The KCM’s batch setSettings applied values with QSignalBlocker, then load() saw no change (in-memory values already updated). Added syncCavaState() called from updateSettings() on every settings reload.
Layout card button flicker at fractional DPI: The Auto-assign and Visibility toggle buttons flickered when hovered at 125% display scaling. The visible: property toggling caused Row geometry reflow that shifted button positions by sub-pixel amounts, creating a hover feedback loop. Replaced visible: with opacity:/enabled: and added ToolTip.delay.

Enhanced label effects for branded shaders: CachyOS, Fedora, Neon, and NixOS Drift shaders had label text bodies that appeared solid white. Text fill patterns used screen-space UV which barely varied within characters, and smoothstep(0.3, 0.9, labels.a) washed to white. Rewrote all four with pixel-space patterns, edge rim detection, and x/(0.6+x) tonemapping. Each shader gets a unique style. Digital shatter (CachyOS), frost crystalline (Fedora), neon tube flicker (Neon), hash grid verification (NixOS).
