It seems Winbox is having issues display correctly on my Windows 7 Professional 64-bit system (I’m using a custom theme. This problem still occurs using the default theme). This only started happening a few weeks ago, however I vaguely remember possibly having this issue with Wine a few months back. Here’s what Winbox looks like when I open it:
(it’s got the router saved from the older Winbox connection window in a previous version)
When I connect to the router, Winbox shows like this:
However, when I resize it, this happens:
The only “workaround” I’ve discovered is to right-click the top bar and add something to it, like so (opening a window within Winbox and maximizing it causes it to only fill the same area as before):
Though, the padlock and green icons don’t show in the top-right corner.
This happens every time I start Winbox, regardless of whether it starts minimized or maximized.
So far, I’ve tried deleting C:\Users\Redacted\AppData\Roaming\Mikrotik, however this doesn’t help. Is there anything else I could delete in case something is corrupt?
I also asked about this over on reddit in /r/MikroTik, however nobody else had experienced this before 
No other applications on my system do this.
Thanks.
