Bug description

Summary

In Files app (Grid view), when scrolling down in a folder with more items than fit on the screen, each time a new row of items loads (after ~5–6 visible rows), the entire grid shifts left by one icon position. Item alignment jumps horizontally on every new row load.

Affected browsers

• Brave 1.83.120 / Chromium 141.0.7390.122 — affected
  (Shields disabled → still affected)
• Chrome 141.0.7390.108 (64-bit) — affected
  (Incognito → still affected)
• Edge 141.0.3537.99 — NOT affected

So this is not caused by extensions or shields, and not universal to all Chromium builds.

Steps to reproduce

Reproduction

1. Open any folder in the Files app that contains more items than fit in one screen
2. Switch to Grid view
3. Start scrolling down slowly from the top
4. After ~5–6 rows, when new rows are lazily loaded, the icons shift left

Expected behavior

Expected

Loading additional rows should not move already rendered rows.

Actual

Every time a new row is appended, the grid jumps left by exactly one icon column.

Notes

• Happens only when there are enough items to require lazy loading (scrolling)
• Does not reproduce on Microsoft Edge 141 using same account and same folder
• Reproduces in Chromium-based browsers even with no extensions and all shields off
