Windows 10 Pro 64 bit (1803)
AMD Radeon RX480 4GB with Radeon Software 18.6.1
Intel i5 3550, 8GB DDR3-1600
Broken: 2.8 Alpha (98d20550897) local build with Visual Studio 2017
Short description of error
When Eevee is the active render engine, tweaking any slider related to material shaders or light sources causes a GPU memory leak (visible with GPU monitoring applications, or even the new Windows 10 Task Manager), and eventually Blender crashes with the following error (on the console):
GPUTexture: texture alloc failed. Not enough Video Memory.Error : EXCEPTION_ACCESS_VIOLATION Address : 0x00007FF76A9E718C Module : D:\blender-git\build_windows__x64_vc15_Release\bin\Release\blender.exe
Exact steps for others to reproduce the error
- Build Blender 2.8;
- Load factory settings;
- Select the default cube;
- In the Properties editor > Material tab, adjust back and forth any shader slider (e.g. Roughness) repeatedly until Blender crashes.
It also happens with previous WHQL display drivers.
This does not happen if the render engine (from Properties editor > Scene) is set to Cycles.
