Thanks for your report and for supporting us by buying WinSCP.
I'll look at it. Meanwhile, you can set a tile size to "small".
I recently picked up the Windows Store version of WinSCP (on Windows 10 v1809) so I don't have to deal with updates anymore, however the WinSCP icon looks very strange when it's pinned to the Start menu. It's much larger than other pinned icons, as you can see in the screenshot. The standalone install looks fine, it's just the store version. I've checked this across two computers, so I don't think it's something specific to one of my machines. Has anyone else come across this?
