Linux: Lubuntu 18: highlight rectangle is black - should be transparent

[RaiMan]

Launchpad question

noticed that in the old versions highlight rectangle was 100% transparent, but now on Windows 10 and Ubuntu 18 rectangle has red-ish filling. I believe this is the reason on Lubuntu18 highlight is showing as a black rectangle.
I know that this is not a critical problem and I can use Ubuntu, but reason for me to use Lubuntu is that it is very light on system resources in comparison with Ubuntu.
So is there a way to configure Sikuli 2.0 to use the old way of highlighting?

This is also happening for me in Windows 10 with version 2.0.1
We use SikuliX for demo automation and screen recording. The red-ish background is a no-go for us at the moment.

What exactlyx do you mean by This is also happening for me in Windows 10 ?

[MiguelDomingues]

Sorry for not being specific.
What I have is this "noticed that in the old versions highlight rectangle was 100% transparent, but now on Windows 10 and Ubuntu 18 rectangle has red-ish filling"

See picture below:

The script is this

pattern = find(Pattern("1575322297453.png").similar(0.70))
pattern.highlightOn()
wait(2)
pattern.highlightOff()

I just tested this with the master branch code.

I did a bit of digging, and submitted a Pull Request: #250
That fixed for me.

As mentioned with the PR:
not the colored fill-in is the original problem, but the solid black background only on Lubuntu.

[RaiMan]

I asked the original complainant on Launchpad, to test the new feature (switch off color fill-in): 0e5a578

I done the test on build 466 from 5 Dec 2019

Settings.HighlightTransparent=True
find(someimage.jpg).highlight(2)

On Windows10: PASS - highlight box is 100% transparent
On Lubuntu18: FAIL - highlight box is still black

Note: I noticed that default value of Settings.HighlightTransparen is False for Windows and True for Lubuntu

[MiguelDomingues]

In version 1.1.4 I had a different behavior.
In that version the background was always transparent. That's why I believed it was a bug.
I was unaware of that setting also.

@ndinev
thanks for the feedback.
So it seems the reddish fill-in is not the problem (but the intended new behaviour ;-).
I will go back and use the complete implementation of 1.1.4 in case of Settings.HighlightTransparent=true

I will report here, when it is ready to test.
