Mandelbrot example not working on Ubuntu
The mandelbrot example compiles and runs but the image is not displayed on both Ubuntu 20.04 and 16.04
I install GraphicsMagic by "sudo apt-get install libgraphicsmagick++1-dev" and build build Wt4.4.0 from sources with "cmake -DWT_WRASTERIMAGE_IMPLEMENTATION=GraphicsMagick ..".
Browser tested: Firefox and Opera. The example runs on Win10 without problems.
Own Code using WRasterImage shows the same behavior.

I go the exact same problem (Wt 4.4++ build from last source)
Solved this by removing and reinstalling GraphickMagick followed by recompillation of Wt (cmake + make)
Now I am able to start using Wt:WRasterImage.
Mandelbrot example still not working but adding img->done(); line 115 of MandelBrotImage.C solves the bug, as suggested here ; https://github.com/emweb/wt/pull/166/
