Hi @Bluebeat —— Thank you for the report. Unfortunately, this looks like a performance issue, meaning that Roon needs a certain amount of video memory to run but for some reason your device is running low, which is causing issues as the interface is rendered.
In most cases, this means too many things are running at once, or something is using an inordinate amount of memory. Does this persist when you restart Roon? What if you quit other applications first? What about after a reboot of the device?
We’re always looking for ways to improve Roon’s performance and we may be able to make this better in the future. For now, we’ve found that in most cases these issues tend to come down to a device (usually in a temporary state) on which the required graphics memory is simply not available. Let me know how you do with the tests above and we can look into this further if you’re seeing this consistently.
