transparent vertical/horizontal lines @ right/bottom
I'm seeing a vertical lines of transparent pixels in some images, on the right hand side and/or bottom.
I have a Hi-DPI screen set at 200% scale.
Whether or not EOG is maximised seems to make a difference in which orientation they appear on and thickness.
One example PNG image of size 408x238 px shows a prominent such line at the bottom, but none noticeable on the right. But when the windows is maximised, a less noticeable (thinner? certainly darker grey) line is visible on both the bottom and the right.
Another image of 1466x726 shows such a line on the right but not on the bottom when not maximized, but when the window is maximized it appears on both as with the other.
Lines also show in fullscreen.
These are not the only two images this happens with, it has been present in all of the handful of images I've just checked whilst writing this.
I am experiencing this under the default adwaita theme as well as arc-theme.
