MacOS Memory Leak: cc-switch

Quick fix

Restarting cc-switch after prolonged use can temporarily restore WebKit.WebContent memory usage; no complete fix has been merged.

Symptom

Section titled “Symptom”
Error output
磁盘缓存很小，但是运行时 WebView 内存没有释放，猜测 WebKit 在处理 RemoteLayerBackingStoreCollection / JavaScriptCore 分配等方面出现了内存泄露的问题
English translation

Disk cache is small, but WebView memory is not released at runtime. This may indicate a memory leak in WebKit when handling RemoteLayerBackingStoreCollection / JavaScriptCore allocations and similar areas.

Cause

Section titled “Cause”

On macOS, this issue accumulates while cc-switch continues running, mainly in WebKit.WebContent graphics layers/backing storage and WebKit Malloc memory; usage returns to normal after restarting.

Reported visible trigger paths include continuous refreshes in Settings → Usage Statistics and repeated layer creation from chart animations. A patch for this path has not been merged, and the reporter explicitly noted that it cannot guarantee a fix for all causes of this issue.

Fix

Section titled “Fix”

  1. Temporary mitigation: restart cc-switch and check whether WebKit.WebContent memory usage returns to normal.

  2. To help diagnose the issue, record the continuous runtime, WebKit.WebContent memory usage, and whether Settings → Usage Statistics remains open with auto-refresh enabled.
