I Use Repeater with encryption plugin and password -> no Warning

One Solution:
click Thrust and write this to "IP".vnc File

FullScreenTitleBar

Resolved (Only with Multimonitor with different DPI)
add "::SetWindowRgn" after DPI change

and save hLastMonitor TitleBar on wrong Monitor

i hope the last changes from me :)

Next
FullScreenTitleBar
changed files in my Onedrive

the size of the FullScreenTitleBar changes with DPI change

I found the Bug
Send SendFullFramebufferUpdateRequest On DPI change before running -> empty picture
I add Autoscaling even in the old Options Dialog

wait with release, i found a problem

merge with git code
Now Autosize scale is OK (no Border, biggest possible window)

Faster and better result for other then 100,200,300% is to use "scale to window" (directX)
Autosize is working with directX in window mode too.

toDo
keep aspect ratio for Fullscreen in directX (Only if Autosize?)

New Viewer Exe in Onedrive

New Option:
Not in GUI, only Inifile
