cast Entire Black Image

Dear Clarius-team, I updated to the newest version 10.1.1, everything is working, also the image callback after connecting the probe. But I receive images containing only zeros (images shown in the app are looking normal). Im using the code for cpp and working on Linux 20.04. Would you have an idea where this error comes from? Thanks in advance:)

This usually occurs when ports are blocked by the firewall.

this one might be different since the callback is actually engaged, but a black image. It may have something to do with the GL rendering, are there any errors in the console that are output regarding GL?

Thanks for your answers. I checked again, the firewall is not blocking. Regarding GL rendering, there are no errors at all which occur.

Seems that the GPU drivers may be the culprit if you can check out this case and see if it will help.

Unfortunately I'm using an Intel GPU and cannot use a Nvidia GPU due to no compatibility to real time linux (which we need to use for robot control). So it seems that from version 10 only Nvidia GPUs are working? With the last versions everything has worked fine. Are there any options to downgrade the firmware of the probe?

Due to some filesystem changes, we prevent downgrades once version 10 is installed. But we will continue to investigate the issue around specific vendors and drivers.

We have a new version out 10.2.2 which we recommend upgrading to - we have not fixed the opengl issue, however this version will allow you to connect to a probe without having to keep the Clarius App at the same version

If you're interested in testing - we would like to provide the next alpha library to test potential fixes. I can put this in the releases section under pre-release.
