Does not works with BenQ EL2870U

The UI is only filled by tool output which is barely readable.

shell output:

Nevermind, works fine. I just need to explicitly goes in the features view manually everytime.
The other view have text rendering issue though.

I apologize that this issue did not get a response when originally posted.

The output you saw was temporarily inserted to diagnose an unexpected /sys state. It should have gone to the terminal (if running ddcutil or if ddcui was run from the command line) and also to the system log. It should not have appeared in ddcui's graphical user interface, which is what you seem to be saying. That would be a bug.

In any event, once the situation was diagnosed, in addition to what is written to the system log, there should be exactly one line written to the terminal. If the GUI is still being corrupted when using libddcutil.so.5.4.0 from ddctutil 2.2.3 please report it. Thank you.

Hey, no problem, thanks.
We can close the issue
