More tests !
So I wanted to see what the video card was capable of (or rather incapable of), so I was recommended by Scali Bohemiq to test a demo named "Kukoo2" because it makes intensive uses of the raster bars
You can grab it here https://www.pouet.net/prod.php?which=1444
Source code and build tools are available here :

The reason why I mention the source code is because I initially couldn't even run the demo, the "Pretro" was starting fine, but then it didn't advance any further, I suspect it's doing *something* with the keyboard as I think it expects a keypress, and that I can't do ctrl + alt + delete for a soft reboot (even while the animation is playing so the computer didn't crash).
So I went into the source code and disabled that "pretro" (line 602 if you're looking to reproduce it).
So I launched my new exe and the music played fine, but my LCD didn't like the signal anymore. So I decided to hookup a CRT and was greeted with this :
So I guess that video card really doesn't like this demo 🤣 ... Well at least now we know this demo just cannot be used on this card. I wonder if other things might be impacted by this ...
Also I think the keyboard situation is really problematic, because it means some other programs won't respond to the keyboard at all.
I even tried to do again ctrl + alt + delete while the 2nd part of the demo was playing (so the one with the garbled video) and it didn't work either so the computer didn't hang at all, it's just not responding to the USB keyboard.
