F39: wxWebView draws text with the background color -> "invisible" page about wxwidgets HOT 8 OPEN

Downloaded wxWidgets-3.2.4 and build locally:
../configure --with-gtk --disable-tests --enable-webview --enable-webviewwebkit --disable-webviewedge --disable-webviewie --without-nanosvg --enable-debug_gdb --enable-debug

from wxwidgets.

I don't see the problem running GTK_THEME=Adwaita:dark ./webview in master: the page is visible, but it also still uses the light mode, i.e. black on white text:

This might be due to WebViewGtk version difference, I wonder which one does Fedora 39 use?

@vadz Tried it your way, did not change anything. The details about the render backend are slightly covered, sorry. I have installed:
webkit2gtk4.1-2.44.0-2.fc39.x86_64.rpm
webkit2gtk4.1-devel-2.44.0-2.fc39.x86_64.rpm
webkitgtk6.0-2.44.0-2.fc39.x86_64.rpm

from wxwidgets.

It could be that WebKitGtk 2.44 has implemented support for dark mode missing in my 2.42 and this breaks this somehow... Sorry, I really don't have time to debug this now.

light mode does not work better:

Take your time ...

This is really unexpected, it really looks like 2.44 broke compatibility in some way.

We probably need to start by looking at their changelog.

It works fine for me on Fedora 39 with the exact same webkit2gtk4.1-2.44.0-2.fc39.x86_64. Maybe something to do with that "unable to construct a complete frambuffer" message.

Needed to upgrade to F40 for some reason. Tried the compiled example WITHOUT modification and it works now.

The package names between F39 and F40 do not show a difference in version numbering:
webkit2gtk4.1-2.44.1-1.fc40.x86_64.rpm
webkit2gtk4.1-2.44.1-1.fc39.x86_64.rpm
Could it be some kind of "global" configuration?
