Hi everyone,
The problem is the following: my local screen resolution is 1366x768, I'm setting server resolution also at exactly 1366x768. When I connect to this server through viewer, set scaling to 100% and switch to full screen - scroll bars appear on both the bottom and the side.
Both server and viewer are TightVNC 2.8.79.
I tested the same in RealVNC, UltraVNC and TigerVNC viewers, and none of then have this issue.
If, for example, I switch scaling to 99% the scroll bars are gone but the picture gets blurry.
This almost certainly looks like a bug and hopefully it can be fixed.
Thank you.
