From e0f326e23f6b96f31ce9e8bbd5b5f2233e6a90ba Mon Sep 17 00:00:00 2001 From: skal Date: Sat, 21 Feb 2026 09:35:33 +0100 Subject: fix(tests): Resolve intermittent SIGTRAP in test_effect_base The test `test_sequence_render` was disabled due to an intermittent SIGTRAP. The issue was caused by the test application exiting before the GPU finished rendering. This commit fixes the issue by adding a call to `wgpuDeviceTick()` after submitting the command buffer. This ensures that the GPU has completed its work before the test finishes. The test is now re-enabled and passes consistently. --- PROJECT_CONTEXT.md | 2 +- TODO.md | 3 ++- src/tests/gpu/test_effect_base.cc | 3 +++ 3 files changed, 6 insertions(+), 2 deletions(-) diff --git a/PROJECT_CONTEXT.md b/PROJECT_CONTEXT.md index 7d219e6..672e18e 100644 --- a/PROJECT_CONTEXT.md +++ b/PROJECT_CONTEXT.md @@ -40,7 +40,7 @@ - **Tools:** CNN test tool operational.
