The PDF in bug 1721949 uses many unique pattern objects that references the same shading many times. This caused a new canvas pattern to be created and cached many times driving up memory use. To fix, I've changed the cache in the worker to key off the shading object and instead send the shading and matrix separately. While that worked well to fix the above bug, there could be PDFs that use many shading that could cause memory issues, so I've also added a LRU cache on the main thread for canvas patterns. This should prevent memory use from getting too high. |
