When you click from the Inbox to Sent, for example, the app doesn't repaint the message header panel area, so stuff just kind of overwrites the existing text which is confusing. Dragging another window around on top of it will erase the bogus text. This is a pretty minor bug but kind of annoying. Reproducible: Always Steps to Reproduce: 1. Click on Inbox 2. Click on Sent Actual Results: Message header panel still shows messages from Inbox with the ones from Sent superimposed on top of them. Expected Results: The panel should just clear and show the messages in Sent Workaround, drag another window on top like an eraser.
Fixed in mail-client/claws-mail-3.7.3-r1
A new Claws version will be out this week, which will be stabilised in 30 days time.
