Form Designer Keeps Moving on Linux Mint
lazarus / 10-Designer

So I have just managed to install latest Lazarus (v1.6.2) and FPC
(3.0.0) on Linux Mint Cinnamon Serena 64-bit, I have it dual boot
alongside Windows 10.

I am not too familiar with Linux and took quite a bit of work getting
Lazarus installed (thanks to help from this forum) but there is one
remaining issue, the Form Designer keeps moving itself when I add a
new control to the form. For example:

- Start Lazarus

- Project > New Project ... > Application menu.

- Form1 Designer at this point is:
  - Left = 390
  - Top = 120
  - Height = 240
  - Width = 320

- Now I move Form1 Designer and resize it to say:
  - Left = 652
  - Top = 326
  - Height = 454
  - Width = 413

- Now I go to add a control from Tool palette at the top, say a
TButton from the Standard tab.

- When I click on Form1 Designer the button adds but the form designer
reverts back to the original dimensions and position:
  - Left = 390
  - Top = 120
  - Height = 240
  - Width = 320

This happens also when adding a control from the View > Components
menu.

What gives? Why does the form designer keep moving and resizing back
to old dimensions and position when adding a control to the form?

Has anyone else experienced this behavior? It is very odd and
difficult to use IDE like this.

As a temp workaround anchor docking and sparta docked form editor
packages seem to work without form designer jumping and changing size.

YUP and like you, my cries for help are being ignored too.

I tried installing the three .deb files in Ubuntu 14.4 and Lazarus is
fine.

Requests for help on Mint forums also being ignored. {sigh}

Hi, I use Linux Mint 17.2 Mate and don't have this problem. May be
MATE does work with GTK 2.X and 3.X.
Cinnamon use GTK-3 and Lazarus 1.6 by default (project, options) use
widgetset LCL "gtk-2".
So, try to change the widgetset to gtk-3. (I really don't know if it's
a solution).

Well at least someone else experienced this too so I know I am not
alone.

Are you using multiple monitor display? I have been having the same
problem since I started using multiple displays in Lazarus on Linux
Mint in a Parallels VM. If I revert to single monitor display the
problem disappears. I hope that helps.

Happens to me as well. Everytime I try to drop a new control on a
form, been this way for many versions. To be honest, it doesn't bother
me that much.

Sometimes they don't jump about if I explicitly set the left/top then
save, close lazarus, reopen it and then add controls.
