[Bug] Widescreen hack does not work with DX11/GL #282

Open diego-au opened 2 years ago

diego-au commented 2 years ago

Enabling "Widescreen Hack" causes a stretched image rather than an extension of the camera / viewport when using DX11 or GL. This issue is not present when using the Vulkan driver.

As Vulkan is not supported on all platforms such as Xbox Series X|S, it would be good to resolve

This issue is very noticeable with Gamecube games:

Widescreen Hack with Vulkan Driver: Notice the hole/opening in the wall on the left is visible image

Widescreen Hack with DX11: Opening in the left wall is not visible as image is stretched image

Yeah I mentioned the issue in #239 (although I should've make 2 separate issues instead of a 2-in-1, for visibility purpose), I tried fixing it myself multiple times but this is too complicated for my very, very limited skills :p I hope someone will be able to fix this at some point...
