[{"error":"Error: NON-FATAL: Lock acquisition failed for /Users/wescopeland/.local/share/claude/versions/2.1.109 (expected in multi-process scenarios)\n at yU_ (/$bunfs/root/src/entrypoints/cli.js:2342:2153)\n at Vs6 (/$bunfs/root/src/entrypoints/cli.js:2342:1233)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-15T20:41:22.303Z"}]

TL;DR

The issue with Claude being unable to read text in screenshots due to low resolution may be related to a recent change or update, and checking the version history or configuration for any changes related to image processing or resolution handling could provide insight.

Guidance

• Review the version history of Claude to see if there were any recent updates or changes that could be causing this issue, particularly around image processing or resolution handling.
• Check the configuration settings for Claude to ensure that there haven't been any changes to how screenshots are processed or if there are any new restrictions on resolution.
• Investigate if the error message regarding "Lock acquisition failed" is related to the issue at hand, possibly indicating a problem with accessing necessary resources or files.
• Consider testing with a previous version of Claude, if possible, to isolate if the issue is indeed version-specific.

Example

No specific code snippet can be provided without more context on how Claude processes screenshots or handles resolution, but reviewing the cli.js file mentioned in the error for any recent changes could be beneficial.

Notes

The provided error seems to be more related to a locking mechanism failure rather than directly to the issue of reading text in low-resolution screenshots. It's unclear if these are separate issues or if one is causing the other. Further investigation into the relationship between these two aspects is necessary.

Recommendation

Apply workaround: Given the uncertainty around the cause, attempting to use a previous version of Claude or adjusting configuration settings related to image processing might serve as a temporary workaround until a more definitive solution can be found.
