Follow-up Comment #5, bug #51442 (project octave):

Could you post 
glxinfo -B

All my computers currently running Gallium with either
amd or nouveau or llvmpipe backends. None of them have 
problem with plotting to either qt or fltk.
Here is one with nvidia:

name of display: :0
display: :0  screen: 0
direct rendering: Yes
Extended renderer info (GLX_MESA_query_renderer):
    Vendor: nouveau (0x10de)
    Device: NVC3 (0xdd8)
    Version: 17.1.4
    Accelerated: yes
    Video memory: 975MB
    Unified memory: no
    Preferred profile: core (0x1)
    Max core profile version: 4.3
    Max compat profile version: 3.0
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.1
OpenGL vendor string: nouveau
OpenGL renderer string: Gallium 0.4 on NVC3
OpenGL core profile version string: 4.3 (Core Profile) Mesa 17.1.4
OpenGL core profile shading language version string: 4.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

OpenGL version string: 3.0 Mesa 17.1.4
OpenGL shading language version string: 1.30
OpenGL context flags: (none)

OpenGL ES profile version string: OpenGL ES 3.1 Mesa 17.1.4
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10

The one that used to give me problem was i7-2600k with integrated
graphics. At some moment I bought ~$50 entry level amd card for it and i do
not have problem with it anymore. I will try its integrated graphics later
today or tomorrow, but I cannot mess
with it at this moment. And I am running Wayland since Fedora 25beta which
probably longer than a year.
