Public bug reported:
What happened:
I ran the 9front installation ISO (here:
http://r-36.net/9front/9front-3853.02ebd469f43a.iso.bz2) in QEMU, with a blank
qcow2, using `qemu-system-i386 -hda 9front.qcow2.img -cdrom
9front-3853.02ebd469f43a.iso -boot d -vga std -m 1G`. During the console boot,
I accept the default display settings (1024x768x16, VESA, PS2 mouse), and
9front proceeds to the GUI boot. However, every pixel is blurred, making text
illegible and the GUI unusable.
What I expected:
Normal pixel rendering / normal display.
Step by step instructions:
0. Install QEMU 2.1.2 (I use Homebrew's bottle, `brew install qemu`)
1. Download 9front ISO (9front-3853.02ebd469f43a.iso.bz2)
2. Create new QEMU image: `qemu-img create -f qcow2 9front.qcow2.img 20G`.
3. Boot 9front ISO: `qemu-system-i386 -hda 9front.qcow2.img -cdrom
9front-3853.02ebd469f43a.iso -boot d -vga std -m 1G`
4. It displays a console boot screen; accept default args (local, glenda,
1024x768x16, vesa, ps2, etc...)
5. GUI is drawn.
6. Pixel are blurred and unreadable
Details:
This bug does not occur when 32 bit color is used, using the 1024x768x32. This
bug does not occur when QEMU is built with SDL (in Homebrew, `brew install qemu
--with-sdl`), although the console portion of 9front's boot runs significantly
slower.
System:
OS X 10.9.5 x86-64
Macbook Retina Late 2012
Intel i7 Ivy Bridge dual core.
Build:
Homebrew's QEMU 2.1.2 bottle, which is build without GTK, SDL, or VDE.
** Affects: qemu
Importance: Undecided
Status: New
** Attachment added: "Screenshot of buggy rendering."
