[BUG] Progress exceeds 100% if framerate is extremely slow

[iovoid]

I tried running FurMark 2.3.0 on software rendering (llvmpipe) for fun, and found a small bug:

The progress bar goes above 100% (315% here) if the framerate is extremely slow (0.003467 FPS here).

Reproduction steps:
- Run furmark using software rendering or other very slow backend. The command I used was

Code Select Expand

LIBGL_ALWAYS_SOFTWARE=true GALLIUM_DRIVER=llvmpipe furmark --demo furmark-gl --benchmark- Wait until the benchmark is complete. Might take an hour.



Program output:
