Mouse Operation Problem in v1.4.4 under Linux

[Wolf Baginski]

I am not sure if this is a question, an answer, or a warning.

I'm running Linux Mint 18.3 with Xfce, an Ubuntu derivative, and problems started after I installed KSP v1.4.4

Graphics settings can mess you up. My mouse pointer started showing in a different position on the screen to the point-of-click. The offset was consistent enough that I was eventually able to change the settings to a combination of matching the monitor pixel-dimensions and having full-screen on. It helped that it was essentially vertical, and you could see the active button light up, both ordinary menu screens and the setting screens.

Since the problem persisted through a clean install, wiped the whole folder and replaced from the zip-file,  it looks like something was being saved elsewhere, but I haven't been able to track down any changes with plausible timing. It couldn't be anything before today.

It only affected KSP. The offset only affects the contents of the KSP window, not the close-window button provided by the OS.

This was happening with an un-modded install, and could very well explain a problem I was having with a mod. Whether the mod triggered the problem, I am unsure, but since it persisted after a clean install that seems unlikely.

(I know, it's not practical to test every Linux version and desktop that is current.)
