User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:59.0) Gecko/20100101 Firefox/59.0 Build ID: 20180219114835 Steps to reproduce: Open the following web page with hardware acceleration enabled: https://appamics.com/tb/test-appamics-canvas.html Actual results: The overlay image should be clipped using a path. However, the full images are painted. Expected results: The path should be used as clip region. Affected: Windows 10 with nvidia GeFoce 1050 Ti graphics card and latest driver. Seamonkey on the same Windows 10 PC. Works: With hardware acceleration disabled. In Windows 10 VM (Parallels) on macOS. Could be an nvidia specific issue.
I see this with Nvidia and Intel. There in 52, with regression range: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=29beaebdfaccbdaeb4c1ee5a43a9795ab015ef49&tochange=f7d5008ee2ab9200052e45ad6ecc3f3a348f7f86
