HeidiSQL Windows opens in huge window

Dear all,

i am facing problems with size of HeidSQL windows once open.

As you can see from picture below the windows size of HeidiSQL opens over the hole two displays - there is no end and it seems that it is not possible to fix the size to one monitor

Iam using two monitors: Laptop and 4k 27" Monitor.

Which version of HeidiSQL is that?

I did an update this morning to the newest version - problem still occurs. This error is since many versions for me.

Something else specific there? Probably high DPI settings, or Linux/Wine?
