Hi,
When changing the logo for our JIRA instance, anything over 30px tall is resized to be 30px tall. This means that you can't upload a logo that looks good on a HiDPI display. This is weirdly hypocritical of JIRA because the default logo is 60px tall and looks great on a retina display.
We tried manually changing the logo on our server to use a 60px tall one, but this didn't work. Does anyone know how to force JIRA to accept a retina-friendly custom logo?
