Hi,

benchmark works well (P2160, GL/VX). But when I click on "RUN" in the FurMark_GUI application, I'm getting this error:
----
furmark: imgui.cpp:10575: bool ImGui::ItemAdd(const ImRect&, ImGuiID, const ImRect*, ImGuiItemFlags): Assertion `id != window->ID && "Cannot have an empty ID at the root of a window. If you need an empty label, use ## and read the FAQ about how the ID Stack works!"' failed.
----

I'm running Ubuntu 24.04.2, Wayland, MSI GeForce RTX 4060 VENTUS 2X BLACK 8G OC, driver 565.77

Any idea?

[JeGX]

No idea, but I'll test again on linux asap. Did you use the latest version 2.6.0?

Same error here, neither GL nor VK works, with IG or DG

- FurMark 2.6.0.0
- Debian, kernel 6.12.17-amd64
- X11, XFCE 4.20
- AMD 8845H with 780M + RTX4060 laptop
- NVidia driver 535.216.03-2


But another computer with Intel A770 works fine

- FurMark 2.6.0.0
- debian, kernel 6.12.12-amd64
- X11, XFCE 4.20
- Intel ARC A770
- OpenGL 4.6 , mesa 24.3.4


2.4.1.0 works well on both computers.

Ok, I have to find the bug and fix it

Hi!

I have the exact same problem (same output) in version 2.7.0.0 on Arch Linux.

Two or three weeks ago I tried to reproduce the bug but no luck. I tested on a virtual machine (virtualbox) + latest EndeavourOS (arch linux). Maybe I have to install EndeavourOS on a real PC to see the bug...

Hi!
I have the exact same problem (same output) in version 2.7.0.0 on Arch Linux.
Do you have the bug with the GUI too?

[vinicentus]

Yes.

The GUI launches successfully and allows me to select the test to use. When pressing RUN, it launches a black window, that then closes, and the console outputs the same message as before. After 2 tries with different tests (gl & vk) I closed the app.

Is there anything I can do to help further?

[JeGX]

Yes.

The GUI launches successfully...

What I wanted to know is if the bug was also present with the GUI (no need to launch the stress test). Because the GUI and furmark share the same code.

Is there anything I can do to help further?

Yes, could you rename the GPU monitoring plugin (dylibs/plugin_gxc_gpumon_x64.so) and run the test again?

[vinicentus]

When renaming the lib you mentioned, the test run successfully when launched from the gui. Normal output in the cli:
