>Description:
With kernel 4.99.16 i can see white or black square instead of cursor and in xterm I can see garbled text. I have rebuild kernel, userland and XFree86. I'm using XFree86 from /usr/xsrc. Disabling agp* in userconf helps. I have intel graphics card:
000:02:0: Intel 82855GM GMCH Integrated Graphics Device (VGA display, revision 0x02)
000:02:1: Intel 82855GM GMCH Integrated Graphics Device (miscellaneous display, revision 0x02)
Earlier 4.99.16 has triggered a panic with agp0 device, but I haven't saved output. 
>How-To-Repeat:
Build 4.99.16 system.
Run X.
See white square
