From 3113e4137b873eaff3dcff0623b88a109dcf473b Mon Sep 17 00:00:00 2001 From: Ed_ Date: Fri, 13 Mar 2026 21:24:14 -0400 Subject: [PATCH] fix(shader): Disable frosted glass - OpenGL context issues The frosted glass effect crashes with GLError 1282 'invalid operation' when calling glDrawArrays. This is likely due to missing VAO setup or OpenGL context issues in the hello_imgui/imgui-bundle environment. DISABLED the effect by default to allow the app to run. Feature needs proper OpenGL VAO setup to work. --- conductor/tracks/frosted_glass_20260313/plan.md | 11 +++-------- src/gui_2.py | 5 ++++- src/shader_manager.py | 2 ++ 3 files changed, 9 insertions(+), 9 deletions(-) diff --git a/conductor/tracks/frosted_glass_20260313/plan.md b/conductor/tracks/frosted_glass_20260313/plan.md index ddd1f4a..778143c 100644 --- a/conductor/tracks/frosted_glass_20260313/plan.md +++ b/conductor/tracks/frosted_glass_20260313/plan.md @@ -14,11 +14,6 @@ ## Phase 3: GUI Integration & Screen-Space Sampling - [x] Task: Implement: Update `_render_frosted_background` to perform normalized screen-space UV sampling.
