Windows Terminal version

1.16.230126001

Windows build number

10.0.19045.2788

Other Software

No response

Steps to reproduce

In my terminal i have 5 tabs where various batch files are continuously running (in a loop).
When I start, the task manager shows me about 100 MB of memory for the terminal.
But the memory consumption runs up by about 100 MB every day!

The batch files don't really do anything special, they copy files or show me network parameters.

Expected Behavior

No response

Actual Behavior

memory consumption increases steadily
