 == Orbot version ==

 15.2.0-RC-8-multi

 == OS ==

 Replicant 6.0 0001

 == Steps to Reproduce ==

 1. Enable llvmpipe in Replicant.  Instructions for this are at
 https://redmine.replicant.us/projects/replicant/wiki/Graphics#Enabling-
 llvmpipe-as-software-renderer .
 2. Run Orbot.

 == Expected Results ==

 Orbot should display normally.

 == Observed Results ==

 Orbot only renders a black screen.  The context menu provided by the
 hardware "Settings" button does display properly, as do the "QR Codes" and
 "About" dialogs available from that context menu.  Orbot's non-graphical
 functionality seems to be working fine.  Orbot seems to be able to read
 the touchscreen fine (I'm able to start/stop Tor by clicking blindly).

 == Other Notes ==

 Compatibility with llvmpipe is important because llvmpipe is the only
 renderer available on Replicant that runs Orfox properly; Orfox (like all
 other Fennec-based apps) crashes with the default Android software
 renderer.  So, right now, in order to change Orbot settings, I need to
 disable llvmpipe and reboot the phone, change the Orbot settings, and then
 re-enable llvmpipe and reboot the phone again before I can resume using
 Orfox.
