Grafana render image has garbled text

We are trying to download images from a dashboard, using the /render/d-solo path, but when it does so, the text in the images are coming out garbled.
our url is like:
https://XXXX:32000/render/d-solo/rN1_wCdWz/_?from=now-5m&panelId=10&to=now
See the attached image. All of the text is garbled.
What do we need to do to fix this garbled output?
