[Linux] Mouse randomness doesn't generate in certain parts of the dialog

[Nojisumire]

Moving the mouse in certain parts of the randomness window (e.g. over the image) doesn't generate any randomness (according to the progress bar), unlike Windows where this is/was not an issue.

Expected behavior

Randomness should be generated regardless of where the mouse is in the window

Observed behavior

Randomness is not generated

Steps to reproduce

1. Move the mouse in the randomness window over certain parts of the dialog (e.g. the image)

I have a .avi I took for Windows in an XP Virtual Machine, but Github doesn't support .avi, so I've had to upload it at a temporary file hosting service: https://x0.at/jhUF.avi
