Ok, sorry, got that wrong - we sometimes get bug reports about the
android emulator (which is a fork of QEMU) here, and at a first glance,
your bug report looked like one of these misguided bug tickets, too.
Anyway, please provide some more information: Which version of QEMU are
you using? Which operating system are you running in QEMU?

Title:
HOST VRAM Leak when performs android-x86 window rotation with Virt-GPU
Status in QEMU:
Incomplete
Bug description:
I will report something strange thing about host VRAM leakage after
anroid-x86 window rotation when it runs with virt-gpu(+ virgl-
renderer)
Please watching below video link.

I don't sure what is the problem...
Here are my tested history
--------------------------------------------------------------------------------------------------
Install android-x86 on I7 desktop PCs with intel UHD GPU - No leak.
Install android-x86 on I7 desktop PCs with NVIDIA GTX GPU series - No leak.
Install android-x86 on guest machine emulated skylake cpu with
QEMU(+virt-gpu, virgl-renderer) - Leak
(HOST CPU - I5, INTEL UHD GPU)
Install android-x86 on guest machine emulated skylake cpu with
QEMU(+virt-gpu, virgl-renderer) - Leak
(HOST CPU - I7, NVIDIA GTX GPU)
COMMON:
In case of NVIDIA GPU : check vram using nvidia-smi
In case of intel UHD GPU : check shared-vram using free cmd
We checked guest android-x86 system down when vram is full after performing
many rotation
-------------------------------------------------------------------------------------------
Is it virt-gpu driver's problem?
I hope someone can help me...
Thanks in advance!!
PS
Here are qemu options I used...
-machine type=q35,accel=kvm -cpu host --enable-kvm \
-smp cpus=4,cores=4,threads=1 -m 4096 \
