inconsistent cursor size over certain apps or windows

[pjbryan]

^ in this first photo, you can see that it is my normal cursor.

^ and in the second hovering over the thinkorswim app, the cursor gets bigger. the cursor gets bigger when i hover over obs too.

this may be a cinnamon desktop issue with high dpi monitors because i never had this issue on gnome.
i have already tried manually setting my mouse cursor theme through command prompt, and entering dconf and manually changing my mouse cursor. tried enabling and disabling fractional scaling in displays (though i dont think that does anything in relation to my cursor), and nothing seemed to work.

p.s. i use a higher resolution monitor, i believe 4k, widescreen monitor
