Slow scrolling in some menus with MATLAB R2018b and R2019a on Windows

Hi,

In some MATLAB windows (figure property inspector, documentation center, comparison tool) I have lags especially for scrolling down the window or interacting with some elements. These lags make documentation center and property inspectior unusable because far too slow. The rest of MATLAB works perfectly well without any performance issue. I don't think this comes from my configuration which is :

• i7-8750H
• 16 Go RAM
• 512 Go SSD
• Radeon PRO WX 4150 graphic card.

I do not have any error message on an external window or in the MATLAB console.

Does anybody experience the same issue ?

Thank you by advance

I have a similar problem, but on MacOS High Sierra and MacOS Mojave. With MATLAB 2019b, scrolling in File/Open, File/SaveAs, and uigetfile() in my programs has slow, erratic scrolling. This is also true of my programs compiled with MATLAB compiler. With 2018a, all is well.

I have the same problem. Dose any one how it can be solved?

No solution for me soo far (on MATLAB 2018b and 2019b). I didn't find anything on the internet. I reinstall MATLAB and tried to change parameters and the problem remains. I can't use some matlab tools properly, so I have to use other tools. For example, to compare two files I use other tools like the one Notepad++ and for help, I use my internet browser.

Making more research and trials, I found that the following commands could help (for livescript, property inspector and documentation center not for comparison tool).

>>s = settings
>> s.matlab.web.LightweightBrowserDefaultType.PersonalValue = 'cef';

I hope this can help.

Something that works for me for the documentation center is to change the "Documentation location" in the preference menu. I chose "Web, on mathworks.com (Internet connection required)" instead of "Installed locally". It seems to solve the lag for the documentation center but not for the other menus (property inspector, comparison tool, live script). It is therfore a partial solution.
