@popcornmix - I've uploaded a script here which will generate an ASS file based on various parameters - as written it will generate an ASS file (test.ass) that displays a 3 line subtitle twice a second. With the default 3-line ASS file generated by this script, I'm leaking 1,048,576 to 2,097,152 bytes of GPU memory every second - GPU memory is exhausted within 4 minutes (gpu_mem=320).

Edit: Script updated to allow sub-second intervals - GPU leaks even faster.
