Add-on Explorer shows a blank window

When I open the Add-on Explorer, it only shows a blank window. But if I move around the cursor, it does change its look (from 'Normal Select' to 'Link Select', as the picture shows) at some places.

Besides, Add-on Manager shows the same problem, while the 'Package App' window works fine. I tried reinstall MATLAB, but the problem remained. (I'm using MATLAB R2018a on Windows 10 64-bit) Recently I used an extended monitor, and I wonder if that's the cause of the problem. In case there is no solution, can I install a .mlpkginstall file manually?

I have a similar problem on Linux. Although in my case the window is black and unresponsive. Starting Matlab with "matlab -softwareopengl" didn't help either.

i have a similar problem on windows. it showed up on matlab2020b and still occurs on 2021b when i installed it to mitigate the issue

Please try to run the following in the MATLAB Command Window:

>> opengl software 

And then try opening the Add on explorer again. It worked for me.

If that works, you can save the preference so that MATLAB always opens with Software OpenGL by running:

>> opengl('save','software')

I have same issue for my newly installed Matlab 2021a. I tried "opengl software " and it didn't work. Is there anything else I can try? I also got blinking blank window for Add-on Manager, Get Hardware Support Packages, and etc. Can anyone help on this?

Hi,

I had the same problem. These commands doesn't helped me. In my case the problem was due to an external screen which I use on my laptop. After disconnecting the latter, the problem is solved.

[Zhong Zhou]

Same. Switching to one monitor mode would display the content of the Add-on page.

[Grigor Pahlevanyan]

Haha, I tried everthing for 2 days straight, never would I have thought it was because I had two monitors. Thank you!

Hi Xiatong,

Please first make sure this is not an issue caused by OS environment, you could try installation on another PC if allowed to confirm if this is reproducible at your side, otherwise, reinstall OS and MATLAB usually would resolve the issue.

I have the same issue on matlab2022b, have any of you guys been able to solve it? the command didnt work for me

[mrutyunjay siddannavar]

For MATLAB 2022B, run the below command before launching MATLAB.

xhost +SI:localuser:root

It worked for me.

[Huseyin Emre Ozgur]

Thank you mrutyunjay siddannavar, your solution worked like a charm. Kudos!
