I have been using dual screen for a while now. But recently my mouse has been changing randomly on my second monitor. When I start my PC theres litterally no problem but after a while the cursor randomly changes to what you can see on the pictures below. I'm not using a custom cursor.
The only difference between the 2 monitors is that one is connected with HDMI and 1 is connected with a DVI kable into a DVI to DP converter on the graphics card. The HDMI monitor is the one ruining it.

(sorry for the bad picture quality, my cursor does not display on screenshots and I couldn't find how to change that)

The picture with the black box is the cursor hovering a textbox.
