Dynamic Lighting Map Reveal

So, for whatever reason, my players' tokens aren't revealing the map. They line of sight lighting works just fine, it's just that the map doesn't reveal where they'be been. The odd part is, the player with an enabled darkvision does reveal the map, making things stranger. Please help?

Hi Startraphell T., This sounds like an old issue (that crops up occasionally) based on what you describe your player is experiencing. Try having the player turn on (or off) his/her hardware acceleration and see if that fixes the issue. Understand this might cause issues with other programs such as video games that rely on it, if they turn it off. How to turn on/off hardware acceleration in Chrome Open Google Chrome. Click Customize and Control Google Chrome > Settings. Click on Show advanced settings and scroll to the System section. Uncheck/check Use hardware acceleration when available and restart Google Chrome. How to turn on/off hardware acceleration in FireFox Click the menu button and choose Preferences.
