There seems to be a memory leak in the device portal's mixed reality capture area.
When periodically calling the photo capture api, the device memory in use increases.
/api/holographic/mrc/photo (POST)
After several photo (30+) captures the device portal stops accepting most api requests.
The photo api returns the following error:
{"Code" : -2147024882, "CodeText" : "Not enough memory resources are available to complete this operation.\r\n", "Reason" : "Failed to take photo", "Success" : false}
Even when having a pause of 60 seconds in between the photo captures, the memory still fills up.
Only rebooting the device fixes the issue.
