[Octave-bug-tracker] [bug #52328] Multiple Plots with QT Backend Within A Loop Fails For Some Plots

[Richard Shadbolt]

Follow-up Comment #2, bug #52328 (project octave):

Hi,

Output from the command line :

# glxinfo -B
name of display: :0
display: :0  screen: 0
direct rendering: Yes
Extended renderer info (GLX_MESA_query_renderer):
    Vendor: Intel Open Source Technology Center (0x8086)
    Device: Mesa DRI Intel(R) HD Graphics 5500 (Broadwell GT2)  (0x1616)
    Version: 17.2.2
    Accelerated: yes
    Video memory: 3072MB
    Unified memory: yes
    Preferred profile: core (0x1)
    Max core profile version: 4.5
    Max compat profile version: 3.0
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.1
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 5500 (Broadwell GT2) 
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.2.2
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

OpenGL version string: 3.0 Mesa 17.2.2
OpenGL shading language version string: 1.30
OpenGL context flags: (none)

OpenGL ES profile version string: OpenGL ES 3.1 Mesa 17.2.2
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10

For both commands regarding LIBGL, the script still fails to plot the curves
for some of the plots. That is, as before, there are 10 plots, but some are
blank, and this is random in which ones are blank. 

Regards,
Shadders.
