Installation showing text fragments after splash screen

[raviasuros]

Hey there,

I'm trying to install OPNsense-21.1-OpenSSL-vga-amd64.img on a Fujitsu LifeBook E448. After selecting the USB Stick on Boot the Installation Splash Screen appears and continues after 2 seconds to multi user mode. When the console output is switching to full screen I can only see white dots all over my screen. Those dots look like text fragments from the console output. I already tried the serial and vga image. Does anyone has a clue how to fix this issue? Can't find anything releated to this on google.

thanks
