Questions regarding QHD+ resolutions

[DerecX0]

Hi, I noticed a rendering issue when playing above 1080p (2560×1440, 4K, and also DLDSR resolutions). During the pre-rendered/in-engine cinematic sequences (not gameplay and not FMVs), a 1-pixel-high line appears along the bottom edge of the screen, showing part of the underlying game renderer. The issue is not present at 1920×1080 and seems to affect only those specific cutscenes. Is this a known limitation, or is there any workaround? I'm attaching two photos of the issue. Unfortunately, I couldn't take proper screenshots because Final Fantasy XIII causes the Windows Snipping Tool to freeze whenever I try to capture the screen.
