here is what happens when I boot with a multiboot image of my OS with grub. I think it is related to the bios function (int 10h, ax = 1110h) that I call to load my graphic character definition I must not return properly to the real mode because it crashed on another machine

may need to learn how to "read" this new kind of character :P

When I switch video modes but forget about redrawing everything to adapt to the new resolution... Gets me every time.

Yeah. :mrgreen: You want a wrapper function which runs the mode switch & sends redraw messages or whatever.

That's one of the best programming accidents I've seen: you should sell the design to a tile manufacturer, perhaps after experimenting with adjusting the contrast a bit.

I'm in the middle of rewriting some core printing functions, and I accidentally broke my text scrolling function. I thought the result looked funny!

(I haven't been on this forum in years, I was super young when I was fascinated with this hobby, and now I'm actually developing my own! It's exhilarating)

The definition of undefined behavior, accidentally putting the top of your stack into %rsp instead of the bottom and constantly being in a stack overflow. This took me forever to debug. Not a super crazy looking breakage but it displayed the panic image slightly corrupted without any of the panic debug info.
