From 00aa5e7f2ec8c7494238fa530e41cb788839a8f2 Mon Sep 17 00:00:00 2001 From: trav Date: Wed, 14 Oct 2026 12:51:38 -0700 Subject: [PATCH] v0.55.0: Kaleidostrobe smooth again; visualizer tile hover controls The cones move only on the plugin's own 25 fps frames again: driving them from fresh audio every refresh made bass-heavy songs twitch (a jump on 84% of refreshes against 41%). The continuous turn, texture crossfade and the GPU big window stay. The tile: a click opens it big (and it stays blank while big); hovering shows a colour wheel (colour / gray / off) and up/down arrows (previous / next visualizer). No more double-click or click-to-cycle. The big album art closes on a click or Esc, like the big visualizer. --- CLAUDE.md | 17 ++- lintunes/__init__.py | 2 +- lintunes/gui/art_window.py | 18 ++- lintunes/gui/preferences_dialog.py | 7 +- lintunes/gui/visualizer.py | 181 +++++++++++++++++++++++---- lintunes/gui/visualizer_kaleido.py | 16 +-- lintunes/gui/visualizer_styles.py | 6 + lintunes/kaleidostrobe/engine.py | 15 --- tests/test_round18.py | 2 +- tests/test_round29.py | 6 +- tests/test_round78.py | 5 +- tests/test_round85.py | 25 ++-- tests/test_round86.py | 191 +++++++++++++++++++++++++++++ tests/test_round9.py | 18 +-- 14 files changed, 414 insertions(+), 95 deletions(-) create mode 100644 tests/test_round86.py diff --git a/CLAUDE.md b/CLAUDE.md index 49972d0..7646e9e 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -186,6 +186,12 @@ persistence) → GUI (Qt widgets that read the manager and connect to its signal share of the width.
