In some cases, the ABRA Flexi desktop application may display incorrectly – windows appear "broken", overlap each other, fail to refresh when switching between them, or remain partially blank (this is typically seen in forms such as the VAT Return).
This issue is caused by a conflict between Java rendering and the graphics card drivers.
What can this look like?
Solution
1. Update
update your graphics card drivers
2. Adjusting the rendering settings (recommended solution)
Open the file:
C:\Program Files (x86)\WinStrom\parametry.txtFind the line with parameters (containing e.g.
-Xmx)Add the following parameter:
-Dsun.java2d.d3d=false
👉 Ideally, insert the parameter before -Xmx, e.g.:
-splash:splashscreen.png -Dsun.java2d.d3d=false -Xmx1g ...
Then save the file and restart Flexi.
