This page only applies to app Twine.
If you see visual glitches often in Twine, turning off hardware accleration may help. You should only do this if you are seeing a problem. As the name implies, using hardware acceleration speeds up Twine's display.
To do this, go to Troubleshooting under the Help menu, then choose Disable Hardware Acceleration. This item will be checked when hardware acceleration is disabled, but changing the setting will only take effect the next time you launch Twine.
You can also disable hardware acceleration with a command-line switch.
