Bug ID: 155431
Summary: Leak: Accelerated ImageBufferCairo doesn't destroy the
used textures
Classification: Unclassified
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Canvas
Assignee: webkit-unassigned at lists.webkit.org
Reporter: magomez at igalia.com

When using the accelerated path, ImageBufferCairo creates up to two textures for rendering: m_texture to hold the buffer content, and m_compositorTexture used to take the content to the ThreadedCompositor (when enabled).
These 2 textures are passed to cairo to create a cairo_surface using cairo_gl_surface_create_for_texture(), but cairo doesn't take their ownership, so currently they are not being destroyed when the ImageBuffer gets destroyed.
