OpenGL passthrough fails followed by QEMU crashing with Windows 98SE guest
sedme0 opened this issue · comments
When I try to run any OpenGL program, I get the same error, and QEMU always crashes. So far, I've tried Half-Life 1 (unpatched retail release) and a benchmark program called 3dexercizer (it was the first one that came up when I searched for an OpenGL benchmark for Windows 98). I'm using QEMU 5.2.0 on Debian 11. My QEMU settings are as follows:
./qemu-system-x86_64 \
-no-hpet \
-no-reboot \
-m 1024 \
-rtc base=localtime \
-drive file=win98se.qcow2 \
-device ich9-usb-ehci1 \
-device usb-tablet \
-device VGA \
-display sdl \
-M pc \
-device AC97 \
-netdev user,id=net0 -device rtl8139,netdev=net0 \
-L pc-bios
Here's the log:

Same thing happens when I use qemu-system-i386. I'm not using KVM because it makes Windows 98 unbootable on Ryzen CPUs.
Kill the line.
$ grep -nH ALPHA_SIZE ../qemu-5.2.0/ui/sdl2.c
../qemu-5.2.0/ui/sdl2.c:824: SDL_GL_SetAttribute(SDL_GL_ALPHA_SIZE, 8);
It is believed to be the GREEN Goblin Linux OpenGL driver issue. Feel free to report the bug for them to fix it or fork and maintain a working build for them. The BLUE & RED camp are fine.

That works! Thanks! Well, it works for Half-Life, that benchmark just shows a striped image of blue and black vertical bars. I'm not really concerned about some random benchmark, though. Are there any side effects to removing that line?
No problem with 3DExerciZer. Just need to make sure OpenGL extensions is limited to Year 1999.
