If I have the DT theme set to eg. Xfce-4.0 (light) then start :observer, then change the theme to eg. Vertex-Maia-Dark, observer changes that window correctly to dark font on white background. But if I start :observer with the Dark theme already set it shows the white-on-white font.

I also noticed when I changed from Dark to Light theme, not only did it not change the white font to dark on the Processes tab, but the background text color in Memory tab turned dark creating a similar problem.
So is this a bug in observer or wxWidgets? Workaround? Thanks!

also, dunno if it’s related but I just noticed when I start the observer in IEX it shows this:
13:39:17: Warning: Mismatch between the program and library build versions detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1011,wx containers,compatible with 2.8),
and your program used 3.0 (wchar_t,compiler with C++ ABI 1012,wx containers,compatible with 2.8).

I don’t get that warning but then again I have 2.8 installed (for other reasons as well).

Yes, I have it on Gnome with dark theme, had a similar problem with DBeaver but was able to customize it, no such luck with observer. Though activating a row makes it readable so I just went with it

I know this might come off wrong, but macOS is getting dark mode in a few months, wxwidget 3.1.x will support it https://trac.wxwidgets.org/ticket/18146 - I also believe latest OTP has added build support for wxwidgets 3.1(Allow building with wxWidgets-3.1.1 by dgud · Pull Request #1768 · erlang/otp · GitHub) - so I would assume this issue will get a lot more traction soon (including from me :/)
aka replace hardcoded colors with function similar to this Dark Mode Patches · wxWidgets/wxWidgets@c6523f0 · GitHub that then returns the color dependent on dark mode or not etc. (or do the check in erlang)
excellent opportunity to contribute to OTP, I just don’t have the time, nor the environment to reproduce currently..

I don’t have the knowledge and/or time atm to fix this, so for now I’ll just doc it somewhat, what looks like problem is with the hard coded values.
as pointed out above, using system colors as this example change:

Instead of BG_EVEN and BG_ODD in the observer code (create_attrs() fuction) below:

Sorry for kicking a dead horse here.. Is it possible to enforce a light theme via env vars somehow? This is driving me nuts.
Edit: found something brutal, yet better than status quo:
