Input pauses when using Terminus in panel

[bitmagewb]

When using Terminus in the panel the input pauses and lags on my Macbook. If I hold down a key and let it repeat this can be seen in bursts of aaaaaaa(pause)aaaaaaaa(pause). It also occurs in normal typing.

Running Terminus in a tab is much less laggy. Non-Terminus (ex: iTerm2) terminals have no lag.

Environment:
Sublime Text, Build 4180
Macbook Pro, Sonoma 14.6.1

The debug output from holding down 'a' seems to show input 'piling up' at intervals with multiple aaa's being processed in a block:
