Fine Black Seams #43

Open ChthonVII opened 4 years ago

ChthonVII commented 4 years ago

(I'm using the retroarch core of bsnes-hd. Not sure if this is the right place for such bug reports.)

I'm getting fine black seams at random places. I have trouble spotting them with the naked eye, but shaders can wind up sampling from them, and then I sure as heck notice. For instance, when scaling up to 4K, xbr-mlv4-multipass is sampling from the seams and generating some pretty noticeable black artifacts.

Enabling "show overscan" is a partial workaround in that it seems to remove the seams, but then you're stuck with the overscan.

If the issue is (most likely) related to the core, not purely to ReatroArch itself, this is the right place. (I maintain both the core and standalone version in this repository, avoiding code duplicates.)

First of all please make doubly sure the core and RetroArch are up-to-date. And, if possible, try reproducing the issue in the standalone version. (Standalone is preferred, a lot, for the following requests, but not a must.)

What I need for analysis is screen-shots and save-games from at least 2 places where the issue occurs. Then I can have a look at it and try to find the cause.

Thanks for reporting and for any efforts in helping me reproduce the issue.
