1. You are using an Intel(R) integrated GPU
This problem only affects Windows. Intel integrated GPUs work correctly with Genymotion on Linux (Ubuntu/Fedora) and macOS.
Genymotion Desktop rendering has compatibility issues with the display drivers for Intel HD Graphics and Intel UHD Graphics integrated GPU on Windows.
If your computer use this GPU for display, you should consider using a different PC with an NVIDIA or AMD GPU, or switch to Linux.
2. You are using a laptop with an Intel integrated GPU and an NVIDIA/AMD discrete GPU
NVIDIA Optimus and AMD Switchable Graphics fail to set Genymotion Desktop to use the High performance discrete GPU.
To fix this, you need to force Genymotion Desktop use the High performance GPU. For detailed instructions, please refer to How to force Genymotion Desktop use the high performance discrete GPU on laptops?
3. Windows power mode is too low
Make sure to set your power mode to Best Performance:
4. The virtual device is too powerful for your hardware
Modern virtual devices, such as Samsung Galaxy S10, run on Android 10 and are set to use 4 CPU cores and 8192MB of RAM. If your PC does not have at least 8 core CPU and 16GB of RAM, it will likely run out of resources and cause instability and random crashes.
To fix this, you can either choose a less powerful device, such as Samsung Galaxy S8 on Android 8.1, or create a Custom Phone/Tablet with less processors and memory.
For more details, please refer to Genymotion Desktop Quick Start guide.
5. Upgrade VirtualBox
Genymotion Desktop 3.2.1 has been tested with VirtualBox 6.1.14 and includes an installer with this version, but since Windows 10 has received several updates which may cause issues with this version.
If none of the above helped, upgrade VirtualBox to 6.1.30:
- Uninstall VirtualBox.
- Download VirtualBox 6.1.30 for Windows host here.
- Right-click on VirtualBox installer and select
Run as Administrator.
- Follow the instructions from the installer.
- When finished, reboot your PC.
