BUG：MATLAB2024b got a bug about "uigridlayout"

When I use 2024b to run code:

a = uifigure;
b = uigridlayout(a);
b.RowHeight = {'1x'};
c = uipanel(b);

result is:

Obviously, the border line in the bottom of the uipanel cannot be shown correctly.

For comparison, I use MATLAB 2023b to run the same code, the result is correct:

So strange.

I hope there is something I can do to solve this problem, cause I got a big project and the 2024b cannot be used for this reason.

I am unable to reproduce this issue on my PC of Windows 11 MATLAB R2024b.

Can you share the type of operating system (Windows/Mac/Linux) you are using, or the output of the following command on your MATLAB R2024b command window?

What report the command

rendererinfo

?

[Bruno Luong]

I have tested the code on 2 PCs one with Nvidia graphic card and onother with Intel ARC. Only the Intel ARC has an issue. Note both run on R2024b and Windows 11.

I have reported the issue with Intel ARC somewhere else.

Updated the graphics card driver (Version: '4.6.0 NVIDIA 553.24'), but the issue remains unchanged.

I use two different computer, the problem gone.

It seems my computer is the problem, but why? What can I do to solve this?

There are often bugs related to graphical card, its driver, screen resolution, display scale etc... It seems like a mess to me.

The issue persists even after using another computer:

GraphicsRenderer: 'OpenGL Hardware'

Vendor: 'NVIDIA Corporation'

Version: '4.6.0 NVIDIA 551.68'

RendererDevice: 'NVIDIA GeForce GTX 1660 Ti/PCIe/SSE2'

Hi @Heran Wang,

The issue is not reproducible on my end. The code appears to be working correctly on Windows 11 MATLAB R2024b and the "uipanel" generated is correct. It is possible that this is a low-level UI graphics issue. Kindly refer to the following documentation to debug and resolve this:

https://www.mathworks.com/help/matlab/creating_plots/resolving-low-level-graphics-issues.html

If the issue still persists, as stated by @Stephen23, you can contact Technical Support and report this as a bug.

Updated the graphics card driver (Version: '4.6.0 NVIDIA 553.24'), but the issue remains unchanged.

[Heran Wang]

I change the code into:a = uifigure;

a = uifigure;
b = uigridlayout(a);
b.RowHeight = {'8x','1x'};
c = uipanel(b);

result:

Currently, I am using this solution, but I would much prefer an official fix.

"Currently, I am using this solution, but I would much prefer an official fix."

Then make an official bug report: https://www.mathworks.com/support/contact_us.html
