In xlights open source, we updated from 1.29.1 to 1.30.0 and the listctrl item now does not have any colors. I see listctrl.cpp has had some updates. It is not consistent for our users. It works for some Windows users, but not for others. Anything that might clue us in to the cause?
Focusing on the right side, this screenshot is correct. The second one is not.

After update for a user -- no dark mode, no themes, just basic windows install.

I think it is a local issue and not wxwidgets.

Glad to see that you've found the reason, but it would be interesting to know what it was, just in case anybody else runs into this.

We are following up on it perhaps being a version of xLights that was linked to an older version of wxwidgets vs a new linked version with most recent wxwidgets.

This was broken from 16 November (3842352) till 30 November (907ab5f). Using a wxWidgets version from between those dates could explain the missing colours.
