I have setup MEDNAFEN PSX HW core to use VULKAN. I have defined two overlays so i can switch between them with a keyboard shortcut.
When the core loads the first overlay is displayed correctly as it should, but when i press the shortcut to change to the second layout it doesn’t display at all (and the first overlay disappears).
If i set the driver to use GL the overlays work and change fine. I suspect it is a problem with the VULKAN driver.
I have an AMD RX470 with latest drivers. Any ideas?
