"vr on": 'utf-8' codec can't decode byte: invalid continuation byte

[nicolas.floquet@…]

dear colleague, trying to install the last version (april) of chimeraX we had a problem when shifting to vr by using the "vr on" keyword : 





An error occurred in drawing the scene. Redrawing graphics is now stopped to avoid a continuous stream of error messages. To restart graphics use the command "graphics restart" after changing the settings that caused the error. 

Traceback (most recent call last): 
File "C:\Program Files\ChimeraX2\bin\lib\site-packages\chimerax\core\updateloop.py", line 61, in draw_new_frame 
view.draw(check_for_changes = False) 
File "C:\Program Files\ChimeraX2\bin\lib\site-packages\chimerax\core\graphics\view.py", line 181, in draw 
camera.set_render_target(vnum, r) 
File "C:\Program Files\ChimeraX2\bin\lib\site-packages\chimerax\vive\vr.py", line 435, in set_render_target 
self._check_for_compositor_error('left', result, render) 
File "C:\Program Files\ChimeraX2\bin\lib\site-packages\chimerax\vive\vr.py", line 442, in _check_for_compositor_error 
err_msg = render.check_for_opengl_errors() 
File "C:\Program Files\ChimeraX2\bin\lib\site-packages\chimerax\core\graphics\opengl.py", line 606, in check_for_opengl_errors 
lines.append('OpenGL error %s' % es.decode('utf-8')) 
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 2: invalid continuation byte 







We updated the drivers of the graphic cards (two GTX1080) but the problem persists. 





Please could you help us to solve this issue ? 





thank you in advance.

Fixed in tonight's builds.

New SteamVR versions generate an benign OpenGL error but reporting that error was failing because ChimeraX assumed it was encoded as utf-8 like all other OpenGL strings while in fact it is iso latin 1 (gluErrorString). We do not see this error, it is no doubt because you have a European locale that puts diacriticals on characters.

Thank you it works !
you really do a great job with this software. We adopted it here for the VR capabilities.
Is there any way to do collaborative VR with your soft ? is this in the todo list ?

Thank you !
