Clicking in backdrop window causes flash

Post by DarkKnight » Wed Nov 04, 2020 7:49 pm

Clicking in the backdrop causes all LC stacks to flash. Is there way to prevent this flash?

I see this as well, though I never ever use the backdrop.

Interestingly if you click quickly in the backdrop, only the first click causes the flash. I do not know if this has anything to do with the double-click speed of the underlying OS.

No messages are sent, of course, because you are outside of LC.

There ARE messages sent, mes amis, at least they should! :D

We have:
mouseDownInBackdrop
mouseUpInBackdrop

But that does not explain the flash of course...

Just tested, this also happens on the Mac in LC 9.6.1, but only windows (stacks) that are NOT palettes are affected!?
And the above mentioned messages are obviously NOT sent to the current card, so I consider this a bug!

I added a comment to this bug report:

Klaus.

Yes, about a million, if "IDE Messages" are suppressed in the Message Watcher.

That is where I thought I might find the two "backDrop" messages you mentioned, but they did not appear. If IDE is suppressed, I did get "focusIn", "focusOut", "resumeStack" and a couple of others.

It seemed like unexpected behavior to me. I just wanted to be sure.
