Summary: The user reports that the line jump (arc/gap) feature on crossing connectors is not working consistently — jumps sometimes appear and sometimes don't. This appears closely related to previously reported and fixed issues (#2664, #3675, #3965), but may still persist in certain layered connector scenarios.

💡 Possible Solution Found

We found a potentially relevant solution in a previous issue:

Line jump issues with overlapping/layered connectors have been reported and fixed multiple times. Issue #2664 was fixed in version 21.1.8, and issue #3965 was fixed in version 22.1.19. However, issue #3675 noted the problem can persist in certain layered scenarios. First, try clearing your browser cache and ensuring you're on the latest version of draw.io. If the problem persists, note that line jumps may not work correctly when connectors are directly layered on top of each other — they sometimes only work when lines are slightly offset. Providing a minimal .drawio file that reproduces the issue would help the maintainers investigate further.

🔍 Possible Related Issues

This issue might be related to existing issues:

🔴 #2664 - Line jumps sometimes don't appear as expected around overlapping lines
Describes the same core symptom — line jumps not appearing correctly on crossing/overlapping lines. Was fixed in 21.1.8 but similar behavior was reported again later.

🔴 #3675 - line jumps over layered connectors
Reports the same issue of line jumps not working on layered/crossing connectors, with a commenter noting it still occurred in version 24.6.4.

🟡 #3965 - Lines jump at the branching point of branching lines
Related line jump rendering bug that was fixed in 22.1.19. Could be the same underlying issue if the user is on an older version.

Please check if any of these address your issue. If this is a duplicate, we may close this issue and continue the conversation there.

Do both lines have line jumps enabled?
