Just resizing the window causes a crash? Never seen this, do you have any injector or overlay apps running? Maybe try switching the GPU that ShaderGlass uses if you have iGPU (using Windows Settings), and try updating GPU drivers.
No overlay or injector apps that I am aware of. Just started out of the blue. Never happened with prior versions. I'll update GPU drivers and see about switching GPU. Is it common to get slow down issues when using shader glass with games like Morrowind or Forever Winter? Are there some settings I should tweak to minimize stuttering? I have figured a few workarounds but they either lower fidelity in the extreme or only work for a short time.
