Thanks for retesting.

Even on current GPUs with current Windows 10 WMMD GPU drivers we do get
occasional OpenGL rendering glitches--lately around the RenderContext() double
buffering.

Good, the default GDI Hardware Acceleration for the GPU is functioning--you
won't have to fall back to even slower CPU only rendering.

No current driver support for a Radeon HD 5700, AMD abandoned it as legacy
Catalyst device.

Apache OpenOffice has not implemented any support for OpenGL.

That is old unsupported AMD hardware and their drivers are not going to be the
most functional on Windows 10 which with that AMD GPU and driver should
probably be black listed. Otherwise if you can't upgrade the Graphics card,
might be best to disable OpenGL in your profile.
