the PNG file has 2 colors (black and transparent black), however PNG format has alpha channel while GIF has just transparency. Transparency on black color might be the problem in mono?

Wrote

Because it's Windows ! There may be something internal to Windows coded to check for visibility.

Davide beat me to my first inclination, the transparency feature available in PNG format. However, I run the portable version on Windows and copied the files to Linux, so it's the same folders/folder structure

Question, on Linux, am I suppose to double click on "SMathStudio_Desktop.exe" or "smathstudio_desktop_mono" {no extension}. My version of "smathstudio_desktop_mono" is dated 05/30/2013. The following is what's in that file

#!/bin/sh

exec mono "./SMathStudio_Desktop.exe" "$@"

Please try this build: http://smath.com/file/nbUXn - created for testing only. It has SVG based icons on Boolean toolbox. Windows & Linux. They are not that sharp as before, but at least we can check if they are visible and readable. These icons uses system color for text now (instead of black in PNG images).
If it will be OK all the buttons can be recreated using this technic.

Best regards.

This is how it is on my setup.
Same as previous builds.

Please try and let us know if toolbox buttons are visible now.

All is working excepts those two characters.

Great! Thank you!
This is because of Font missing some Greek symbols. Please try to write these chars in TextRegion and test different Fonts for this Region. I'm sure you will find some Fonts which will allow to render all Greek chars correctly.
Best regards.

Overload, Eric, Pdalet,
Where did you post/upload your fonts in Linux? I am still seeing a mess and not all of the fonts. Being new to Linux, I'm now convinced this is an ID10T error.
I copied my windows 10 fonts directory into my home directory: home/{USR}/.local/share/fonts... unless they go somewhere else

Andrey and Davide,
Thank you for the quick resolution.

fc-list | grep Courier[/code]Maybe you need to force rebuild your font cache too. For this;
[code=bash]fc-cache -f

Congrats, a long mystery is solved.


By the way, maybe that's just my linux setup but;
If I use only the keyboard for "Evaluate symbolically (Ctrl+.)" it is not working too.
Button is fine for calculation, just keyboard combination doesn't work.

I tried this build in my ubuntu 20.04
Mono JIT compiler version 6.12.0.90 (tarball Fri Sep 4 14:02:38 UTC 2020)

also showing the same thing, missing two Greeks characters.

Look for Eric Myers post 4 or 5 above. He says those characters are fixed on his Ubuntu by using these commands.

sudo apt-get remove fonts-liberation2 fonts-liberation
sudo apt-get install ttf-mscorefonts-installer
