Comment 24 for bug 235768

If twinview is the same as "mirror displays" I still have the problem on Ubuntu xenial 16.04 (2018!): When mirroring and zoom, the only thing happend is the cursor/pointer became invisible.
Tried mmalmeida (ex wild_oscar?) solution of comment #9. That "fix" the problem but when displays are not mirrored external display look all stretched and mouse clic are ~ 70 px at the right of where the visible mouse pointer is.
