MATLAB display messed up with large text files

Hi, I have the following issue after installing matlab from the AUR.

Whenever I import a large text file in a MATLAB matrix, if I open the matrix to visualize the content in the data editor all is fine. But, as soon as I scroll the screen gets messed up, as if several instances of the text file were overlapped on top of each other.

Here an example:

All good

All messed up

Notice that: I can read the values fine in the "import data utility". The same thing happens if I try to look at the file by just opening it in the matlab editor, rather than importing it into a matrix. Action on the screen different from scrolling seems to bring the screen back to normal (e.g. selecting something, clicking etc.)

Is this a known issue? Do you know of any settings/workaround to fix it? If I were to report it as a bug, where should I do that?

Re: MATLAB display messed up with large text files

Your links don't quite work.  Google asserts one needs permission to view those files and provides a link whereby you will be asked for said permission.  Most of us here are unlikely to do that.

I don't use Matlab personally, so I've no direct suggestions.   What are your video chip sets and desktop environments?  Are you using a compositor?

Re: MATLAB display messed up with large text files

I have changed the permission and the links are now visible.

I have a discrete/hybrid card Intel/Radeon HD 8750M (Mars chipset) and I am using KDE/PLASMA.

After installing the open driver for the Radeon card and turning on the compositor the bug disappear. The improvement in the desktop environment was sensible, but this lead to overheating of the laptop (with a minimal setup: a few chromium tabs open, a small piece of software running, and a second screen) with temperature reaching 80+ celsius.
