Snapchat back camera video recording extremely laggy

[up south]

Hi, when recording video using the back camera on snapchat the recording is extremely laggy beyond being watchable and the processed video is still laggy and the quality is significantly lower than the display. This is using the standard video quality in the snapchat settings although the lag remains even on lower quality settings. The front facing 'selfie' camera however is fine.
This issue only occurrs using snapchat, recording with the back camera on the default camera app on the htc one is fine so is this an issue on snapchat's part or is something wrong with my camera?
I have tried a fresh install of snapchat and recently updated to version 4.4.2 and HTC sense 6.0 but the issue still remains.
Any help is appreciated thanks in advance.

This may not help, but I'm not having this issue. You've tried a fresh install, maybe go through some of your caches and do some cleaning, or go through your photos and do some transferring.
