Hi!
Today’s update (oct 12) of Plank Dock seems to have removed the magnifying glass effect, and the icons are always the same size, no matter which one you’re pointing to…
Is there a way to revert back to the previous version of Plank please?
Cheers!
Which verison of plank are you using?
you could try:-
Opening Terminal by pressing Ctrl + Alt + t and then type
plank --preferences
you should see this
make sure icon zoom is on.
Also which window manger are you using?
try setting the window manger to Marco with software compositor or Marco with GPU compositor in MATE Tweak.
Hope this helps
Hey there! Thanks for answering so quickly! 
The window in the screenshot you posted is the one that appears when I click Plank’s icon in the dock… And it used to show the “Icon Zoom” option like the one in your picture… But now that’s gone… Even if I launch the preferences window from the Terminal…
I wouldn’t know what version of Plank I’m using, because it doesn’t say it anywhere… 
All I know is that the Software Updater offered me to get a new version today, and I did update it…
My window manager is Marco With Software Compositor, I had never changed that, but when I tried it a couple of minutes ago, all the other ones seemed to have glitches, so I reverted back to that one…
Ok.
Which verison of Ubuntu Mate are you using? 16.04?
(As for me im on 16.04 and I haven't had any updates for plank today 
)
if your on 16.10 beta sorry i cant help.
Click Plank icon then click About then you should see which version your using.
e.g
Also you could try this in Terminal by adding the PPA for Plank
sudo add-apt-repository ppa:docky-core/stable sudo apt-get update
and then restart plank
Try looking at launchpad site to report the error: https://launchpad.net/plank
I'm on 16.04.1, and About Plank shows exactly the same version as the one you have...
So I pasted all your docky lines in the terminal and restarted Plank, but the option for Icon Zoom is still missing... 
Shouldn't have updated it, but how could I know?...
im sorry im almost out of idea's apart from reinstall plank maybe ?
sudo apt-get update && sudo apt remove --purge plank && sudo apt install plank
or install docky instead
sorry 
Well don’t be sorry, you’ve been trying to help me here! 
I’ll try reinstalling Plank from scratch then… Thanks for your efforts!
Nope, install seems to have failed… I don’t know what the Terminal is trying to tell me, but it doesn’t look good! 
Oh well, I guess I’m gonna have to get used to those icons being the same size then…
Or maybe I’ll give Docky a try like you said!
Thanks again!
Give docky a go or try updating your graphics driver maybe.
Sudo apt install docky -y
Or Maybe a fresh install of Ubuntu Mate?
I installed Docky, and it is beautiful! I really like it… The problem now is that I get two docks when I start my machine… I tried removing Plank from my “Apps at startup” panel, but it’s not even there!
Hi @Nunud have you sorted the problem with the two docks ?
(If not try changing the interface to Ubuntu Mate in Mate Tweak
Then right click the bottom panel, Then click Delete This Panel from the menu and click Delete.

Then you should only have one dock showing.)
Hope this helps
Thanks! But now I have a new story to tell! Docky just plain stopped working (I was adding docklets when it died on me), and even a clean reinstall won’t bring it back to life! And even thought I have only one (lame) dock now, I gave your tweak a shot, thinking maybe it would fix the magnifying thing somehow… But nope!
So I guess I’m stuck with this “one-size-non-dynamic” version of Plank no one else has! 
Where did even come from? How come this thing installed on one machine only?
I’m stating to think that my machine might be haunted!
ok.
If i was you i would back up my personal data ( e.g home folder) and do a fresh install of the OS.
making sure all data on the hard disk wiped.

Welcome @digger-yu to the community!
Hi, @digger-yu,
Plank effects are provided by compositing window manager. As far as I understand, LXQt is using Openbox by default, which is not compositing.
I have plank 0.11.89-4ubuntu1~22.04 installed and working fine with compositing enabled in window manager. It does not look like an Ubuntu base issue or a Plank issue. And it is definitely not a MATE Desktop issue.
Yes, it's not a problem. Thank you for your answer.
I found this passage.
For desktop effects, shadows, transparency and else a compositor has to be enabled. Kwin and Xfwm4 provide their own compositor, for openbox or other Window Managers 'picom' (active fork of compton) can be used.
