:display(warning): FrameBufferProperties available less than requested.

[GeYuhong]

After upgrading the system from 16.04 to 20.04, the rendered image is very sluggish and completely unusable. When running the program, the following prompt appears:
:display(warning): FrameBufferProperties available less than requested.
requested: depth_bits=1 color_bits=3 red_bits=1 green_bits=1 blue_bits=1 alpha_bits=1 multisamples=8 back_buffers=1 force_hardware
got: depth_bits=32 color_bits=24 red_bits=8 green_bits=8 blue_bits=8 alpha_bits=8 multisamples=4 back_buffers=1 force_hardware force_software

How can I solve this problem, thx
