Right column in gallery empty after close

[whyboris]

Seems like for at least one person, after re-opening the app, the right-most column in the gallery is empty.

I suspect because of some division and rounding error, there is 1 pixel too-little space for the last column, so instead of (for example) 5 columns, only 4 are shown with an almost-wide-enough-space for the last column.

Step 1: replicate somehow, then fix 🤞

🥳 I figured out the cause: zoom level

If you zoom in (via settings, 3rd tab, "Change the app zoom level") or zoom out.

Upon opening the app the gallery videos "Thumbnails view" will have extra space to the right of the thumbnails and will have fewer columns than needed if you zoom in, and empty space to the right with the correct number of columns when zoomed out.
