The screenshot function is broken with Vulkan

Citra Support
1

Issue:
Monster Hunter 4 Ultimate runs much smoother with much faster load times for me with Vulkan rather than OpenGL. Unfortunately, as I noticed today, the screenshots are black voids with Vulkan on. Most of my screenies are now irrecoverably null. I am not quite sure if this affects other 3DS games using Vulkan as I do not play them on Citra.

System Information

The black screenshot was taken via Vulkan. The discernable one displays the same scene, but with OpenGL instead of Vulkan.

Nope, no screen tearing. And OpenGL had no issues taking screenshots with VSync off.

This is reproducible on my end. So I’ve passed it along to the developer.

Oh, didn’t notice this reply until just now! It appears that at some point during this 8 day gap, it was fixed. Thank you so much!
