SparkChess should look and work perfectly on any browser released in the last 3 years. We test it thoroughly and make sure there are no issues on Chrome and Chromium-based browsers (Microsoft Edge, Opera, etc.) as well as on Safari and Firefox.
There are isolated reports of the board not displaying correctly and in some rare cases missing images. The known conditions are:
- older Microsoft Edge with high contrast mode enabled;
- Chrome (or another Chrome-based browser) with a Dark Mode extension.
Extensions can affect your browsing experience in unexpected ways. If you have extensions enabled, try loading SparkChess in an incognito (or private) window, without extensions. It should run fine. You can also try disabling one extension at a time to see which one is misbehaving.
