Title:
glxgears performance drops to 1 frame per second, but still reporting
60fps
Status in “nvidia-graphics-drivers” package in Ubuntu:
Confirmed
Bug description:
So I was running glxgears, a tool to measure performance of the graphics card.
It was showing animations in maximized size quite nice, but when I took the
console window I used to start glxgears and moved it over the animation and
kept moving the performance rate dropped.
While moving windows the framerate seems to be down, but the reported frame
rate in the console was always like 59-60 fps.
Also when using ALT+TAB to switch to other applications I notice
performance drops in glxgears, (like only a few frames a second, you
could definitly count the frames in a second.)
