Originally created by @radu-matei on GitHub (Aug 18, 2019).

Environment

Windows build number: Windows [Version 10.0.18963.1000]
Windows Terminal version (if applicable): installed from Store

Any other software?
Ubuntu on WSL2

Steps to reproduce

  • open an Ubuntu tab in the Terminal

  • the memory allocated to the Desktop Window Manager starts growing

  • it grows at a rate of around 1 GB / 10 seconds without stopping

image

  • closing the WSL2 tab and opening another one (PowerShell for example), the issue goes away.
  • using the same WSL2 distro and shell from another terminal app (VS Code, for example), issue is not present.

Just upgraded to 18963, mostly similar setup worked fine for 18950.

EDIT: The issue goes away after turning useAcrylic off.

Actually, we’ve been seeing reports of this on newer insider builds of windows regardless of WT being used 😄 thanks!

I can confirm this is not a terminal issue, but a Windows one, related to transparency settings.

Closing - thanks a lot for the hint!

FWIW, I created an issue in the Feedback Hub - if anyone else experiences this, disabling all transparency settings is a known workaround.
