| Subject: | [Octave-bug-tracker] [bug #63748] Qt graphics toolkit cannot create OpenGL rendering context |
| Date: | Fri, 3 Feb 2023 03:43:08 -0500 (EST) |
Follow-up Comment #4, bug #63748 (project octave):
Using the system OpenGL and Qt toolkit after using "imshow(1)" a frozen figure
is created and by clicking on the figure the CPU ugage gains to 100% for near
40 seconds and then these warnings are printed:
octave:1> imshow(1)
octave:2> warning: opengl_renderer: Error 'invalid operation' (1282) occurred
drawing 'text' object
warning: opengl_renderer: Error 'invalid operation' (1282) occurred drawing
'text' object
warning: opengl_renderer: Error 'invalid operation' (1282) occurred drawing
'text' object
warning: opengl_renderer: Error 'invalid operation' (1282) occurred drawing
'image' object
warning: opengl_renderer: Error 'invalid operation' (1282) occurred drawing
'axes' object
Now CPU usage is near 0% but the command prompt cannot be seen and I should
use Enter to make the command prompt visible.
The fltk toolkit works without any error.
