Are you referring to this?

https://blog.martin-graesslin.com/blog/2015/01/why-screen-lockers-on-x11-cannot-be-secure/

If so, I see your point, but I don't think this is as serious of a
problem on Qubes as it is on other systems. Brief summary of points
from the blog post and responses:

Screen lockers on X11 cannot be secure because they...

1. Can be prevented from starting.

Since the screen locker runs in dom0, and only trusted programs run
in dom0, this will never happen maliciously in Qubes (unless dom0
has already been owned, in which case it's already game over).

2. Can be spoofed.

VMs cannot enter fullscreen mode without user permission, so a
fake screen locker in a compromised VM cannot successfully
spoof the real locker in dom0.

3. Cannot prevent other windows from grabbing screen content.

Qubes' GUI isolation prevents exactly this, regardless of whether
the screen locker is active.
