If I set the render image dimensions to something too large, then when Eevee gets to rendering the first sample, my screen would black out (backlight still on) and then some seconds later Windows would come back and the Blender window would be white. Checking on task manager, Blender's CPU and GPU usage is at 0% and killing the process is the only way to close Blender. Rendering at a smaller image dimension would proceed as usual (mark that in both cases, the VRAM usage is 100% and some system RAM is used as well.
- AMD Radeon R5 Graphics
- AMD Radeon R7 M340 (which was R8 M445DX before a driver update and Blender sees it in Preferences as 'AMD Radeon R5 Graphics')
VRAM: 512MB Blender 2.8 in all the betas I've tried (Q4 2018 - Now) Scene has volumetrics btw
