Hello, I am unable to see the analog signals on the software, but the decoded digital data is visible. What could be the issue ? I tried new patches as well as restarted the program multiple times.

@mstharunreddy Sorry about that! Do you happen to be running on Linux?

This was a recently reported issue, and we’ve provided a workaround in the link below:

> Hello, logic pro 16, using Logic 2.4.14 on linux ubuntu 24.04, I encounter strange bug : logic capure are displayed, but analog one are not. The measures are done, since when I flight over the analog capture zone, contextual data show me the voltage, but the trace is invisible, or the same color than background. I tested with all channels, and problem is the same. Any clue to resolve this bug ? Thanks Alexandre

Hope that solves the issue on your end as well!

@mstharunreddy The workaround I linked was tested and confirmed on Ubuntu. Can I know what Linux distro you are using?

Also, have you tried running the command below?  
`rm -r ~/.config/Logic/GPUCache`

In case that command doesn’t work, can you share its output?
