Subject: Re: [9front] Patch for libframe and acme to eliminate redrawing body of documents when typing in the tagline.
Date: Thu, 20 May 2021 11:53:48 -0700 [thread overview]
Message-ID: <386823F2052FD52B32A2A9927CA40EEC@smtp.pobox.com> (raw)
In-Reply-To: <CAD5632C-1695-4029-906D-5FAD3DD4591F@icloud.com>
I haven't looked at the patch closely, but would this also fix the
redrawing of body when other windows in acme are hidden? For example
when 'Mail' running and its window is hidden, the body text of the top
acme window has artefacts shown when a new message is received.
