Regression range

• This is not a recent regression since I was able to reproduce it on Firefox 67.0b17. I'll provide a regression range asap, in case there is an old one.

Additional notes

• I’ve tried to reproduce this issue on a different machine with the same Graphics NVIDIA GeForce 210 and Intel Core i5-3470 (3.2 GHz) Processor but without success.
• My machine has AMD FX(tm)-8320 Eight-Core Processor × 8
  (3.50GHz) and NVIDIA GeForce 210 Graphics
• see the attached txt with about:support data from my computer
• windows and mac platforms are not affected

I tried the STR in comment 0 on Ubuntu 18.04x64 with the following. But I could not reproduce the problem. And from the crash place, it seems related to driver/gpu specific problem.

• 68.0.2
• 69.0b15
• 70.0a1 (2019-08-20)

Bugbug thinks this bug is a regression, but please revert this change in case of error.
