Shader-errors on Alt-tab back to game

I frequently "crash" when Alt-tabbing back to Path Of Exile; crash as in POE starts throwing error dialogs, which prevent ever getting back to POE window. I end up having to kill the still running process.

The crash stars with the "This D3D Device has a non-zero reference..." error dialog, then proceeds directly to the following "Fatal Error" alert boxes:

Error loading shader: Shader/DownScaledParticles.fx E_OUTOFMEMORY

1. I am playing the non-Steam version
2. I am playing in fullscreen mode

If you switch to windowed-full most, if not all, of your crashes will go away. It's worked for many others.

Yes, but because you are now "windowed", your framerate drops dramatically. Windowed-Fullscreen is the devil's mouthwash.
