macOS Sequoia 15.7.1
Sublime Merge Build 2112
Initially, the “Loading changes…” message appears. After that, a very large diff is displayed:
Shortly afterward, Sublime Merge becomes unresponsive, requiring a force quit.
Running git status in the terminal shows no pending changes.
I can reproduce this issue 100% of the time. For comparison, the Git diff view in Visual Studio Code works without any problems.
Thank you for your help!
