[#4257][7.60] Resolution / mouse input issues in borderless-windowed under Linux

[spacecoyote99]

Hey all,

I run X4 under Linux Mint in borderless-windowed mode on a 4k screen. Hadn't played in quite a while and started the game today and noticed my mouse-clicks were off, when I click the event is registered offset from the cursor position. Checking the video settings I see that when borderless-windowed mode is selected the resolution looks too high (see screenshot: https://i.imgur.com/YrYaEUQ.png), it should be standard 4k, 3840x2160.

I've seen this issue before in other games, so I turned off my desktop resolution scaling and that indeed fixes it (after a game restart) Resolution looks normal and mouse works as expected.

So the workaround for now is to do turn off my desktop scaling, start the game, then turn desktop scaling back to 200% after which the game works fine until I restart it.

This happens in vanilla 7.60 as well as 8.00 beta. Strangely I never had this issue in the past (last time I played was when 7.10 was new)

Here's my vulcaninfo https://pastebin.com/raw/K1Npiu0M No save because the issue is already visible on the starting menu, it's not save related.
