[GAMEPLAY] Mouse cursor bugs when playing Rek'sai

Recently I decided to try reksai since hw was on free champion rotation. But I encountered a bug where around mid game my mouse cursor bugs and turns into a grey vertical dotted line. I tried to alt-tab away from the game but the bug persisted to my desktop. The only way I could fix this was to restart the computer, but it would be tiring to restart my computer every time I play reksai. I do not know what triggers the bug, but it only happens when playing Rek'sai. On the Internet it said that changing my game to borderless and enabling mouse trails in the mouse settings would fix my problem, and it did but now my mouse feels buggy/delayed. Is there a possible solution to this without the enabling of mouse trails?
