Good morning! Thank you for posting in the Final Fantasy XIV Technical Support Forums.

We apologize for the delay in response to this issue. The error you are describing may occur when DirectX crashes. The crashing of DirectX may be caused by a variety of issues. We would suggest lowering the graphics settings in game, as the intense graphics in dungeons or high volume areas could cause the crashing.

Please try the following:
- Try switching to DirectX 9 by selecting the ‘Config’ button on the launcher.
- Please disable overlays and all background programs.
- Perform a clean boot by opening the task manager and select the 'Start up' Tab. Disable everything.

If these troubleshooting tips do not resolve the issue, please provide the following below:
Does this issue only occur on this device?
Have you tried another graphics card and or device?
Does this only happen to one character or all characters?
What happens when you leave the character idle?
