Especially when pasting a .png screenshot - Teams converts it to .jpg (with aggressive compression settings), changing the colours and making straight lines jagged. Compare to Slack, which keeps the .png format, even through resizes for smaller windows (and makes the original image available to view).
The engineering team is continuing to work on adding support for multiple accounts on desktop clients. We will first launch support for 1 work/school account and 1 personal account so users can enjoy Teams for work and personal side-by-side. Windows and MacOS. Support for multiple work accounts is still being worked on and will come at a later date.

Thank you for your feedback. The team is currently planning for this work, we will share an update as soon as one is available.
