A single complete Framebuffer Object with matched formats and explicit sync keeps off-screen rendering on the GPU. Learn the minimal setup, trust boundaries, and failure checks.
Learn how to identify and fix silent stalls in WebGPU compute pipelines caused by incorrect buffer usage, missing synchronization, and platform-specific limits.
I am building a pipeline where OpenGL renders into a shared texture and an OpenCL kernel post-processes it each frame, using cl_khr_gl_sharing with objects created via clCreateFromGLTexture. The context is created with the platform-specific GL context properties, and the device reports the sharing extension. The specification describes an explicit ownership
The goal is to reduce host‑GPU synchronization latency in OpenCV pipelines while ensuring that GPU buffers allocated as UMat are never inadvertently exposed to host code. Lazy‑mapped UMat (the default) postpones the actual transfer until the data is first read on the host, which can avoid unnecessary copies but introduces variable stalls when the first acces
