I've been trying for two years. Please.. someone get real

I’m running MacOS Big Sur. 11.6.4
Mac has 16 GB Ram and 2.6 GHZ Dual core.
Standard mac applications installed. No other browser slides down my screen except Brave. I use Chrome, Opera GX, Firefox, Vivaldi, Edge, and Safari all with no issues. Everyone who has tried to help in the past year has always started wiith the premise that it must be my OS. It is NOT my os. It is my browser. There is a bug in Brave that makes it slide down the screen 50 pixels every time I download. My Brave install has blocked 530,000 trancker and saved me 9.8 GB of data. But I will walk away if this issue can’t be fixed. it is like having someone slap me in the face every time I hit send!
