BackendFlagsRendererHasVtxOffset flag is not working

[Cardroid]

If the size of the data is larger than a certain size, there is a problem that the ImPlot does not draw.

bug-ffmpeg.mp4

It's part of my initialization code.
(I referred to ocornut/imgui#2591)

func InitImgui(title string, width, height int) {
	Context = &ImguiWContext{}
	Context.context = imgui.CreateContext()

	io := imgui.CurrentIO()

	// io.SetConfigViewportsNoAutoMerge(true)
	io.SetConfigFlags(imgui.ConfigFlagsDpiEnableScaleViewports)
	io.SetBackendFlags(imgui.BackendFlagsRendererHasVtxOffset)

	io.SetIniFilename("")

	imgui.PlotCreateContext()
	imgui.ImNodesCreateContext()

	Context.imBackend = imgui.CreateBackend(imgui.NewGLFWBackend())

	// logger.Tracef("imgui.CurrentIO().IniFilename()=%v", imgui.CurrentIO().IniFilename())
	// logger.Tracef("io.IniFilename()=%v", io.IniFilename())

	Context.imBackend.SetTargetFPS(60)
	Context.imBackend.SetBeforeRenderHook(beforeRender)
	Context.imBackend.SetAfterCreateContextHook(afterCreateContext)
	Context.imBackend.SetBeforeDestroyContextHook(beforeDestroyContext)
...

The flag does not appear to be working properly.
I'd appreciate your help :)

What's your giu version?

I'm sorry that I didn't put any important information on it.

I'm only using cimgui-go because of the bug in giu
And I'm currently using the code on ptxmac/cimgui-go/tree/ptx_fixes due to a problem that cimgui-go is not building on Windows (#206)

The reason was that the opengl version was 3.0.
It works well when it is fixed at 3.2.
