+HOST VRAM Leak when performs android-x86 window rotation with Virt-GPU
+
+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!!
+
+Here are qemu options I used...
+
+-machine type=q35,accel=kvm -cpu host --enable-kvm \
+-smp cpus=4,cores=4,threads=1 -m 4096 \
+-drive file=ctb0319.qcow2,format=qcow2,if=virtio,aio=threads \
+-device virtio-vga,virgl=on \
+-device qemu-xhci,id=xhci -device usb-mouse,bus=xhci.0 -device usb-kbd,bus=xhci.0 \

+This is the *upstream* QEMU bug tracker here. If you've got a problem with the android emulator, please report these problems to the android emulator project instead. Thanks.
+
+To Thomas Huth,
+
+This is not android problem, qemu or virt-gpu  problem,.
+-------------------- our test log --------------------------------------
+Running android-x86 on I7 bare metal desktop PCs with intel UHD GPU - No leak.
+Running android-x86 on QEMU(+virt-gpu, virgl-renderer) - Leak
+------------------------------------------------------------------------
+
+Also in case of a guest linux, it also have leak after windows manager rotation.
+
+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?
+
+I tested many qemu & linux versions....
+
+in case of qemu,
+2.12
+3.10
+3.12
+4.0.0
+All versions I tested have same problem....
+
+also I tested many versions of linux 
+ubuntu 18.04 18.10
+centos 7
+fedora 18 19
+rhel
+
+Actually it is not only problem of windows rotation, if home launcher refreshed, vram usage is also up...
+
+I think it related gl related functions...
+
+so I don't sure it is qemu-virt-gpu problem or virt-gpu driver...
+
+That is why I already report this problem to android-x86 devel forum and author of virt-gpu drvier...
