I would not expect changing to opengl to help this at all.

Something in the flow is failing to close files after use. It could be a bug. If you have a custom read function then you should check to be sure that it closes the file after it reads from it.

this is the bug in matlab2017a, so switching to matlab2017b or higher will help in this case

The reason for the error messages is because the number of files that are open exceeds the limit on the maximum number of files that can be kept open.

While MATLAB does not have a limit on the maximum number of files that can be open, this is a restriction set by the operating system. Consult your system administrator for information on how to change this limit.

To resolve your issue, close every file with a FCLOSE command after using it. refer https://in.mathworks.com/matlabcentral/answers/101187-why-do-i-receive-too-many-files-open-error-messages-after-several-hours-when-executing-code-which
