Problem reproduced with a fresh Ubuntu 21.10 Live USB (booted with X, whereas I use wayland on a daily basis) :
with both 2 snap versions of chromium available in Ubuntu store :
97.0.4692.71 (latest/stable)
98.0.4758.9 (latest/edge)
My hardware is quite classic, so yes I'm probably not alone to suffer of this broken drag'n'drop :
Ryzen 3600X
Radeon RX 5700 XT
4K monitor (I tried to put it in 1080p, with no scaling : nothing changed)
