Enabling OpenGL for GUI doesn't work on old laptop
QEMU start command is:
qemu-system-x86_64 -enable-kvm -m 2G -cpu host -smp 2 -cdrom ./linuxmint-20-mate-64bit.iso -boot d -vga virtio -soundhw hda -display gtk,gl=on
and QEMU crashes immediately on startup and gives these error messages:
qemu_gl_create_compile_shader: compile vertex error
0:2(10): error: GLSL ES 3.00 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES
qemu_gl_create_compile_shader: compile fragment error
0:2(10): error: GLSL ES 3.00 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES
qemu_gl_create_compile_shader: compile vertex error
0:2(10): error: GLSL ES 3.00 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES
qemu_gl_create_compile_shader: compile fragment error
0:2(10): error: GLSL ES 3.00 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES
If I remove "gl=on" it will boot. Does this just mean that this hardware is too old to run QEMU with OpenGL enabled in GUI, or is this a bug?
Host OS is Debian 10, computer is a Lenovo laptop with Core i5-520M CPU and its integrated Intel HD graphics GPU.
QEMU version is 3.1.0 from Debian repositories.
