Research direction
No source file or test is named. Start by reproducing the issue in RetroArch 1.20.0 with the nearest neighbor filter, moving the cursor near the top-right position on Arch Linux; compare behavior across the listed window managers and confirm whether the diagonal seam appears. Done means the display is pixel perfect without the reported seam.
