Hi @espresso0000, glad to see you here ! Thank you for your test and feedback, we should have a fix for that in the following days, I'll let you know!

Thank you @patrickelectric , looking forward to testing it out with the new upgrades. Preparing for a cave dive Mar6-8 with the Ping360 & 1D to see what they can do.

Hi @espresso0000, We have a new continuous release with the fix: https://github.com/bluerobotics/ping-viewer/releases/download/continuous/pingviewer_release.zip

Can you kindly test it and see if you have the same problem ? If so, please share the GUI log. You are using a different video card from us, so the log is really helpful to understand and fix any problem for you : )

@patrickelectric The fix was successful, Ping360 functional, chart rotation also confirmed functional. Selecting the Ping1D crashed a few times before it functioned. Attached is 2 gui log files utilizing the continuous release.

The patch #889 had the opposite effect for me: adding the line precision mediump float gives a pink square.
