A vertical line shows up in the main menu when using SDL Vulkan

Game or games this happens in

None

What area of the game / PPSSPP

Zoomed in:

Reproducing this bug is fairly annoying: you have to horizontally resize the window until you see a line pop up. Unless you have a 1080p screen, in which case running PPSSPPSDL --dpi 1.3 (giving you 1477px window width when maximized) reproduces the bug consistently.

The OpenGL backend doesn't seem to have this bug.

I remembered seeing such line on an old PC game (Carmageddon 2) which occurred when i use enhancement from AMD driver settings (like sharpening or something, i forgot since i don't have AMD GPU anymore)

Do you perhaps have enhancement being enforced at AMD driver settings?

Hm, that's quite curious - do you see this with the other background settings, or with a background image?

[hch12907]

Doesn't seem to happen with other background settings, only when using Waves does this problem occur.

OK, I think it might just be a bug in waves then. Should be relatively easily fixable, I'm leaving this tagged for 1.17.
