Windows Not Rendering in Flexi (Black Screens – Windows)

Application windows appear black or content fails to render

Written by Petr Pech

This issue may occur particularly on computers with AMD Ryzen processors with integrated graphics. It is caused by a conflict between Java's graphics rendering and the graphics card driver.

This issue is very rare and has typically been reported on Windows 10.


How to fix the issue:

  • Open the file:
    C:\Program Files (x86)\WinStrom\parametry.txt

  • Add the following on a new line:

-Dsun.java2d.d3d=false
  • Save the file and restart ABRA Flexi


Alternative solution (if the above does not help):

  • Replace the parameter with the following:

-Dsun.java2d.opengl=true


Summary:
The issue is caused by Java's graphics rendering. Modifying the parameters changes the rendering method, which resolves the error.
