blinking and strange horizontal pixel lines when moving pages up or down

hello my problem is widespread, recently i took my pc to shop because of some system problems, shopkeeper updated my windows 11 to newest version before update i think i had version from before 2025 i think, anyway many old programs i had saved stopped working or started to have problems if they worked, i had to instal new Firefox too because i completely lost the old one, and the problem i had while watching youtube was weird white blinking sometimes, it was very annoying, i searched online for solution and found out that i should turn off hardware acceleration, blinking stopped but now i see weird horizontal line in the middle of my screen while looking at pictures and moving them up or down or watching movie that moves up and down too, i dont mind turning acceleration back on but then resolving blinking while watching videos on Youtube my windows 11 version 25hc GPU Nvidia RTX 3060 driver updated 23.04.2026 version of driver 32.0.15.9636 firefox version 151.0.1
