You may need to resize the window, as it doesn't always refresh for me on the
first paint event.
Just a quick follow-up: as wtj found after several experiments,
changing wxGLCanvas initialization to `local canvas =
wx.wxGLCanvas(frame)` fixes the initial rendering issues.

I have the following test script that is working for me (it requires
luagl library you can find online along with the binaries):
require("wx")
require("luagl")
local frame = wx.wxFrame(wx.NULL, wx.wxID_ANY, "wxLua + LuaGL Demo",
wx.wxDefaultPosition, wx.wxSize(450, 450), wx.wxDEFAULT_FRAME_STYLE)
local canvas = wx.wxGLCanvas(frame, wx.wxID_ANY, {},
wx.wxDefaultPosition, wx.wxDefaultSize, wx.wxEXPAND)
local context = wx.wxGLContext(canvas)
local function render()
context:SetCurrent(canvas)
gl.ClearColor(0, 0, 0, 0)
gl.Clear(gl.COLOR_BUFFER_BIT)
gl.Begin('TRIANGLES')
gl.Vertex( 0, 0.75, 0)
gl.Vertex(-0.75, -0.75, 0)
gl.Vertex( 0.75, -0.75, 0)
gl.End()
canvas:SwapBuffers()
end
canvas:Connect(wx.wxEVT_PAINT, render)
frame:Show(true)
wx.wxGetApp():MainLoop()
