Matlab Beep at zooming in plot and evaluating variables

I recently started noticing that, when clicking zooming buttons in a plot, matlab starts producing 'error' beeps. However, no error is printed to the command window, and also the zooming works without any problems.
I experience the same while in the variable editor and double clicking fields of a struct (to open them). This constant beeping is slowly driving me crazy and as of yet i have not been able to find what's causing it.
but that turns it off if a delimiter is incorrect during coding, which is not when I hear the beeps.
Can anyone tell me what is causing these beeps and perhaps even better, how to turn them off?

And unsolved.
getArrayEditorBrushCache.m is the source of error. It tries to "shade" entire row in the editor, but error pops up. Right now, commenting the following lines in the said m file seem to be an option (to get rid of the error). You can do so if you also don't have time to fix the problem.
If you don't have an array in a struct, then you may not see this error.
% % If any cell is brushed, the entire row must be shaded % if ~isvector(I) % I = repmat(any(I,2),[1 size(I,2)]); % end % if ~isempty(subsstr) % eval(['I = I' subsstr ';']); % end

Unfortunately the code in the answer is not readable. Which lines are commented and which are not?

The lines to comment out appear to be 39-44. I get this same error, it is quite annoying.

I also receive this error. I have a structure with substructures:
A.B(n).C with C being a [1 x n] double.
When trying to open C via the workspace and "dbstop if error" is enabled Matlab R2018a stops at line 43 in
getArrayEditorBrushCache.m
43 eval(['I = I' subsstr ';']);
Quit Debugging or Continue repeats the error:
43 eval(['I = I' subsstr ';']);
43 eval(['I = I' subsstr ';']);
43 eval(['I = I' subsstr ';']);
43 eval(['I = I' subsstr ';']);
43 eval(['I = I' subsstr ';']);
43 eval(['I = I' subsstr ';']);
I'm not able to look at C at all due to the error.
This reminds me of a previous error I encountered where matlab stopped at the line "drawnow" in the print command. This was partially solved by adding a pause (0.02) command before every print.
Edit: A condition that may or may not contribute to this: - I use matlab via a NoMachine client on a central server

I have this problem as well on R2017b under Windows.
Double-clicking variables to view them in the Variable window succeeds, but produces a beep as well.
Sometimes beeps occur when scrolling through a long list of rows in the Variable viewer (whether by using the mouse wheel, or pressing PageUp/PageDown on the keyboard)
It's tremendously annoying.

The term "recently" is a secure indicator, that you did change something (intentionally / unintentionally / without being aware). As soon as you found out when this has happened, there is a chance to find out what it was. Perhaps you have overwritten a builtin function (see https://www.mathworks.com/matlabcentral/fileexchange/27861-uniquefuncnames)?
Did you try to catch a silent error without output to the command window by
dbstop if all error

I suspect the error with the plots is linked to monitoring a variable as well.
Do you still have it is you close the "Variables" window/tab?
