WinDbg ST of crashing OpenGL rendering of the Fade slide transition

So this continues to be an issue.

With recent Intel DCH driver 26.20.100.7323 on Intel HD Graphics 620 continue
to get OpenGL crashes rendering slide transitions.  Another WinDbg Stack Trace
attached.

On Windows 10 Home 64-bit en-US (1903) with
Version: 6.5.0.0.alpha0+ (x64)
Build ID: 790b5de8941d8f8d98c73ed1343289d7220211ad
CPU threads: 4; OS: Windows 10.0 Build 18362; UI render: GL; VCL: win; 
Locale: en-US (en_US); UI-Language: en-US
Calc: threaded


Simple transitions are fine, but consistently crash with these more complex
transitions:

Fade,
Iris,
Vortex,
Ripple,

etc.

Launching soffice.exe from Cygwin with an 
'export SAL_LOG="+INFO.vcl.openGL+WARN"' env set
unfortunately a "2> soffice.log" output ends empty after crash.

Is my syntax wrong for that, or is there no DEBUG info to be had from the TB77
builds.


An Interesting Sidenote with these recent builds of master, that the
Skia/Vulkan rendering has no crash with these transitions. But is affected by
checking/unchecking the Hardware Acceleration control. With HA checked, the
Skia/Vulkan rendering drops a text box from the rendering--and flashes it back
up at the end.  With out HA checked it renders the entire source master and
text annotation smoothly.
