I have a very simple program like so:
import simplepbr
from panda3d.core import *
from direct.showbase.ShowBase import ShowBase
loadPrcFileData('', 'gl-check-errors true')
class Demo(ShowBase):
def __init__(self):
ShowBase.__init__(self)
#simplepbr.init()
demo = Demo()
demo.run()
This produces a grey window that I can click and drag to resize indefinitely.
However, if I add simplepbr.init() into the script and rerun the program, I can only resize the window once, and afterwards the following error arises:
▶ python test.py
Known pipe types:
CocoaGraphicsPipe
(all display modules loaded.)
:display:gsg:glgsg(error): GL error 0x502 : invalid operation
:display:gsg:glgsg(error): An OpenGL error has occurred. Set gl-check-errors #t in your PRC file to display more information.
(... and the error repeats itself)
If I add gl-check-errors #t to my PRC file I get the following output:
▶ python test.py

Anyone know what’s up? This is my OS:
Thanks in advance.
