[check] OpenCV: ScreenShot BufferedImage to Mat: intermittent error j
< nsrcs && src[j].depth() == depth
Status in Sikuli:
In Progress
Bug description:
I am trying to figure out this intermittent error that sometimes shows
up after the script has run for some time:
[error (27/02/2019, 17:38:38)] Error caused by: Traceback (most recent call

This is running on Windows 7 64 bit
Standard SikuliX installation on 1.1.4 latest nightly build. No custom
libraries or any fancy stuff. The "C:\build" does not exist on this machine,
but not sure if that is a problem, it just refers to the original source file
pre-compilation perhaps?
I've attached the image file thats being used in that search function.
Note that it was saved as PNG using Paint after it was cropped from
the original SikuliX captured file.
I don't see any other correlations with something else happening at
the time these errors are thrown. They seem fairly random to me.
Initial research suggest something to do with OpenCV mixChannels not
accepting the particular image format/colour depth or so on. But It
could be because something else of course?
