Gamma problem in v1.90.2

Hi, thank you for your reply!

I tried your suggestion and installed the glfw backend (glfw and pyglfw on PIP). It does solve the issue with the GammaRamp, but it unfortunately leads to new problems:

First, the mouse can no longer be initialzed:

  File "/home/usb/Dokumente/experiments/myexperiment.py", line 60, in <module>
    mouse = event.Mouse()
  File "/home/usb/miniconda3/lib/python2.7/site-packages/psychopy/event.py", line 578, in __init__
    self.setVisible(visible)
  File "/home/usb/miniconda3/lib/python2.7/site-packages/psychopy/event.py", line 772, in setVisible
    w.set_mouse_visible(visible)
AttributeError: 'LP__GLFWwindow' object has no attribute 'set_mouse_visible'

Commenting out the mouse initialization temporarily for more debugging there is a new problem with text stimuli. Apparently, a pygame font is used but not found?

3.5219     ERROR     Couldn't find font  on the system. Using freesansbold.ttf instead! Font names should be written as concatenated names all in lower case.
e.g. 'arial', 'monotypecorsiva', 'rockwellextra', ...
Traceback (most recent call last):

    bold=self.bold)
  File "/home/usb/miniconda3/lib/python2.7/site-packages/pygame/sysfont.py", line 320, in SysFont
    return constructor(fontname, size, set_bold, set_italic)
  File "/home/usb/miniconda3/lib/python2.7/site-packages/pygame/sysfont.py", line 243, in font_constructor
    font = pygame.font.Font(fontpath, size)
pygame.error: font not initialized

I can imagine to install a missing font or to switch to a different one, but I have no clue how to deal with the mouse problem. Have you had anything like this before when using pyglfw?
