I hve a 4k 49inch TV just giving context and information. But I play the game / mod in 1080p but yesterday I noticed that my cursor is small like when you use 4k resolution and have a tiny cursor but I realised it shouldn't be small as it is in 1080p and should be normal size.

So yesterday and exited and started the game several times but one of the time I clicked the left mouse on the loading screen then when the main menu came up the cusrsor was back to normal 1080p size.

But when I came on today I did the same thing again left clicked when it was going through the loading screens etc. but the mouse has gone back to 4k size.

Anyone had this issue or know what might be happening?
