I tried the genesys backend from the official 1.0.29 release and it
works fine. Please make sure that makes it into 20.04, which right now
is still the broken 1.0.27 experimental version.

@fermulator: Thanks for confirming and, of course, for pointing at the
applicable upstream fix.
Unfortunately it seems like the fix in Ubuntu 18.04 is not sufficient
for some LiDE 100 devices, so the PPA will keep being useful to some
users.

@Ananth: That was disappointing, but thanks for letting us know. The
version you mentioned for bionic has the very same patch as the disco

@CoderGuy: Which Ubuntu version did you
@gunnarhj I have `CanoScan LiDE 100` scanner with this problem on
18.04.3 LTS (bionic). I tried the above mentioned PPA. It does not solve
the issue.
`libsane-common` version is `1.0.27-1~experimental3ubuntu2.2~ppa`. I see
version `1.0.27-3.2...` for later ubuntu versions which is not available
@CoderGuy: Excellent!
Then we need a sponsor so this update can move forward. I'll try to ping
someone on Monday, if nothing happens before then.

I've just verified the package in the PPA and like Simon I can say that
it resolves the issue on LiDE 200 devices. I made 10 scans and the bar
