Mailspring doesn't remember window size Linux

When reopening Mailspring it opens maximized instead of remembering previous window coordinates.
I would also expect the first email in the message list to be selected on launch, but no emails are selected.

Setup

Mailspring 1.17.4. Ubuntu 25.10

  • OS and Version:
    • Installation Method:
  • Mailspring Version:

Additional Context

with version 1.18 mailspring no longer opens maximised but it always opens at the same size, a small window in the centre of the screen. even when manually dragging the corners to create a new size, then closing and reopening, it doesn’t remember it.

so the bug is still here.
