Could you test it with Vulcan using the last stable release?
There has been some work on the Vulkan driver so it’s possible you are running into a new bug here.
Another issue you which may be exacerbating the problem is that an ENORMOUS amount of data is being pushed through the shader pipeline 
[INFO] [Vulkan filter chain]: Creating framebuffer 2048x2048 (max 1 level(s)). [INFO] [Vulkan filter chain]: Creating framebuffer 6144x6144 (max 1 level(s)).
These two lines are telling me the core is outputting 2048x2048, then the scalefx part of the chain is upscaling to 6144x6144. This is a lot! This is what in the past has often caused crashes because the video card runs out of memory. You may want to check out your settings on bsnes to see if you can get it to output snes native resolution if you aren’t using fancy mode upscaling.
Also I should note that shaderfx tends to work best at using an incoming native resolution.
Also a question, were you running this specific game and core with the same preset successfully before?













and thanks for all your help. I’m quite of a perfeccionist , and just want it as close as my CRT looks. But I know that is only quite of gamma and deconvergence what needs perfectioning now and I soon will be there. Thanks for all the patience and info you give me. It’s really an honor…
