My page render perfectly 90% of the time, but sometime, it render completely broken like this (text blurred for privacy)
And, one again, the screen above render properly 90% of the time, except in cases such as these. I could provide plenty of other exemple, but the main idea is there. It is important to note that it is completely independent from the browser (it can even happen in Figma).
BUT the problem here's quite big because it make user testings impossible in responsive mode since we can have these random glitches at any time
