The pcboot panic error when clicking on F2 graph

[arteze]

When you touch F2, a graph opens, allowing you to move the mouse... Then when you click it, it closes and returns to the console state, and at that moment pcboot panic appears.

Version of qemu:

I have qemu 5.1.0 installed, and it works here. Clicking the mouse just does this: https://www.youtube.com/watch?v=0A7oH9iY0P0
It also works fine on a retrocomputer with a SB AWE64 I have here, and an asus eeepc, minus the sound because it has AC97 audio.

That doesn't mean there is no bug, I just can't reproduce it at the moment. So I'm leaving this bug report open for future investigation.

I just installed qemu 5.2.0 and I still have the same problem.

Now I get an error in the qemu, but despite that error, the floppy.img works.

Failed to open module: /usr/bin/../lib64/qemu/ui-gtk.so: undefined symbol: gdk_display_get_monitor_at_window

Anyway, I still have the click problem, maybe it's because of the libraries I have installed.

I have managed to resolve the gdk error, for that I had to update gtk, pango, vte, icu68 and, libunistring.

With all this, the click problem still exists.

The error occurs when moving the mouse in a certain area of the screen.

I wanted to adapt it to another screen mode, with another resolution and different bits of depth ... But I see that the mouse sees double.

I invite you to try the following code.

"The mouse sees double" because you switched to a 24bit per pixel mode, and you're still trying to use the same code which used to draw a mouse cursor in a 16 bit per pixel mode.
