No text on some dialog buttons when using net481 EDSEditor on Linux with mono

[goberhammer]

Describe the bug
The version of EDSEdtor.exe found on the net481 directory of the latest release works almost perfectly in Linux, with the major problem being that some pop up dialogs have buttons without text.

I've looked for solutions on the web and found several suggestions, but none worked.
What I've tried so far without success:

• installed MS truetype fonts (apt install ttf-mscorefonts-installer && fc-cache -f -v)
• export MONO_MWF_USE_XIM=1
• export MONO_THEME=clearlooks
• export MONO_WINFORMS_X11_FONTSET=1 (even if I'm on Wayland)
• export MONO_FONT_FALLBACK=1
• export GDK_SCALE=1
• export GDK_DPI_SCALE=1.0
• export MONO_HACK_DPI=96

I suspect this to be a mono bug when showing system dialogs, but it seems to happen only with small multi choice dialogs, not with full dialogs (i.e. the file selector dialog is displayed correctly), so I don't know if there is anything that can be done on your side, but any help would be really appreciated :-)

To Reproduce
Steps to reproduce the behavior:

1. download latest release 4.2.3
2. install mono-runtime (e.g. apt get mono-runtime)
3. go int net481/ directory
4. execute: mono EDSEditor.exe
5. create a basic project, export to od.h and the export again: the confirm dialog has no YES/NO text

Version used
release 4.2.3, net481

Expected behavior
Text should be visible

Additional context
Ubuntu 25.10

I've digged a little more and found this is a known bug in libgdiplus 6.1:
