[BUG] Claude Desktop + claude.ai: Projects grid leaves stale painted fragments after scrolling

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet
• This is a single bug report (please file separate reports for different bugs)
• I am using the latest version of Claude Code

What's Wrong?

Note: this is a Claude Desktop / claude.ai UI bug (Projects grid), not the Claude Code CLI.
It reproduces in both Claude Desktop and claude.ai in Chrome.

Scrolling down and back up in the Projects grid leaves stale rendered content painted over the
grid. Because it reproduces in both Claude Desktop and claude.ai in Chrome, this appears to be
in the Projects grid component rather than the desktop wrapper.

Stale content remains painted over the grid, in one of two forms:

1. Stale fragments — portions of cards from rows further down the list render at the top of
   the viewport, overlapping the real first-row cards. In the desktop app the stale layer is
   horizontally misaligned with the live grid: the ghost card boxes over the first row sit
   slightly to the right of the real cards (roughly 15–45 px), while a further ghost date label
   lands in the left margin, outside the grid entirely. In the browser the ghost boxes are
   nearly aligned horizontally (at most a few px to the right) but shifted upward, so ghost
   titles and date labels sit above and over the first row. Which cards appear varies between
   attempts.
2. Clipped top row — the topmost cards render with their upper portion cut off.

Frequency

• Desktop app: I have not yet observed a clean scroll-down / scroll-up cycle.
• Browser: roughly half of attempts, and streaky — several consecutive clean renders, then
  several consecutive broken ones.

The difference in rate between the two platforms, and the streakiness rather than clean
randomness, suggests a timing-sensitive interaction between scroll handling and paint.

What does NOT affect it

• Scroll speed — no difference between slow and fast.
• Scroll distance — partial scroll and full scroll to the bottom yield the same result. Scrolling roughly one card row plus a few pixels still reproduces it; the exact minimum has not been pinned down.
• Gesture continuity — it occurs even within a single uninterrupted drag: press and hold the
  scrollbar thumb, drag down, drag back up, release only at the end. This rules out anything
  keyed to the end of a scroll gesture (pointerup, momentum settle, debounced re-render on idle).

Clearing conditions (desktop)
Clears on any forced repaint — alt-tab, or opening and closing another window over the app —
but never on further scrolling.

Desktop launched with --disable-gpu
The bug does not go away; it gets worse:

• Every scroll cycle paints a different set of stale fragments.
• Stale content appears outside the grid columns entirely — a project description fragment in
  the left margin, date labels past the last column on the right.
• A white rectangle renders at top center. Unlike the other artifacts it survives window
  occlusion, clearing only on switching tabs within the app and back.

Software rendering reproducing it more severely, plus the browser reproduction, rules out a GPU
compositing or driver cause.

What Should Happen?

After scrolling back to the top, the grid re-renders cleanly, showing only the current cards.

Error Messages/Logs

Steps to Reproduce

1. Open the Projects view (Claude Desktop, or claude.ai in Chrome) with enough projects that
   the grid scrolls.
2. Scroll down. A partial scroll is enough; scrolling all the way to the bottom gives the
   same result.
3. Scroll back up to the top.
4. Observe stale card fragments painted over the first row, or the first row clipped at the top.

Desktop: reproduces on every attempt so far. Browser: roughly every other attempt, in streaks.
Reproducible across app restarts.

Additional Information

Environment

• Claude Desktop: 2.2553.1 (MSIX package)
• Browser: Chrome 153.0.8010.53, claude.ai/cowork/projects
• OS: Windows 11 Pro 25H2, build 26200.9457
• Hardware: ASUS ROG Strix GL703VD — i5-7300HQ, 16 GB RAM
• Display adapter in use: Intel HD Graphics 630, driver 31.0.101.2140 (WDDM 3.1)
• NVIDIA GTX 1050 present but not driving the display
• Display: 1920x1080 @ 120Hz, 100% DPI, DWM DPI scaling disabled
• Theme: light

Additional notes

• Reproducible across app restarts.
• DPI is 100% with DWM scaling disabled, so not a fractional-scaling artifact.

No repository file, test, or entry point is identified, and the report states that the bug is in the Claude Desktop and claude.ai Projects grid rather than the Claude Code CLI. First reproduce the scroll-down and scroll-up sequence in the Projects view; done means the grid returns to the top without stale fragments, clipped cards, or persistent painted artifacts.
