Can't Turn Off LC Backdrop

Ever since I turned on the backdrop in LC (to white) in Ver 8 DP 16 (on windows 8.1) it has been behaving erratically.

But there does not seem to be any way to turn the backdrop back off! Even the "Restore To defaults" button does nothing. It is extremely frustrating.

IGNORE THIS POST - turned out to be a windows thing. The view setting was not turning the backdrop off, but it was something in widows causing it to stay in place. Turning Backdrop OFF and then restarting LC cleared the backdrop. I hate windows :-)

It's never too late to try Ubuntu. :)

Cross-platfrom tools like LiveCode let me deploy to Windows, Mac, and Linux from any of them I happen to be enjoying in a given week. Lately I've been working on Ubuntu and having a good time with it.

Funny! As a matter of fact I'm trying lubuntu since yesterday, and the backdrop appears in front of everything. If I didn't have a second screen I would've had to kill lc in the console...

Which version of LiveCode are you using? The issue you described was reported as fixed some time ago, but unfortunately a less onerous issue in which the backdrop isn't sized correctly has regressed since:
http://quality.livecode.com/show_bug.cgi?id=16131

The team is working on these, so I'm hoping they'll be addressed in v8,0 soon.

Why Lubuntu specifically, instead of Mint or Ubuntu?

It has re-broken I am afraid. :-)

LC behaves flaky (on windows) when backdrop is up. You can turn it off in view, but it re-appears every time at the start of LC. There is no setting for "no backdrop" in preferences, and the "reset preferences to default" button does not reset anything, as near as I can tell.

Watching the weirdness when backdrop is in place, I get the feeling that messages are being interfered with, or reacted to by wrong stack.

Richard, it's LC8 dp 16. I didn't install LC7 yet.
and why lubuntu? I don't know... I'm a little more familiar with lxde and they say it's superlight.
I must say I quite like it so far. Even have windows on a virtual machine now!

This has reappeared in 8.1.7 rc1 and 8.2.0 dp1
Resetting all preferences clears it, but it returns when live code is opened again.
How can I turn it off permanently?

You could try deleting the preferences file, from my understanding, Lc rebuilds it on restart.

Deleting the preference file did not work.
Is there a cache somewhere? I am on OSX 10.12.6

If I remember right, LC changed the behavior so that on first launch (when there is no current prefs file yet) it will show the background by default. If you already have a prefs file, it should honor the setting. I have never seen the backdrop because I had a previous prefs file already with that setting turned off. But if you installed with no prefs file in place, it sounds like there's a bug that isn't retaining your new choice.

If there was no LC installation on your Windows machine before this started happening, I'd report it. Or maybe report it even if you already had a prefs file. If my guess is correct, deleting the prefs file would make it worse because LC would consider it a "new" installation.

My bad if it does make it 'worse', my assumption is that if something was wonky with the previous prefs file, having it create a new one and then changing the setting should *fix* it.

Of course, if you already can't get rid of the backdrop, then I don't see how it could be made worse if you still can not.

Normally you'd be right, deleting prefs is the first line of attack. But in this case the problem could be due to the new default behavior. It's a deviation from the norm.

FWIW in v8.2dp1 under Ubuntu 14.04 the backdrop works well, off by default and on when I use the "set the backdrop..." command.

Did you already have a pre-existing prefs file? I think the default-on behavior only happens with a new install. But I'm working on what may be a faulty memory of one of the release announcements recently.

Also, I'd guess the OP is using the menu item rather than the message box, so there may be a disconnect in the menu itself. Who knows.

Just found this:

Sounds similar. If you follow the thread to the end, Mark Wieder had a sequence of steps that fixed it.
