I also experience this slowdown, running debian testing on a quad core
Q9550 with plenty of ram and a separate nvidia graphics card that does not
use shared memory. No other drivers besides those included in the dist
installed afaik.
Running firefox with a few tabs open does not cause any
The slow down may also be caused by a too slow CPU.and/or low system memory.
I run PKS reporter, WSJT-x + MSHV at the same time (together with more power hungry programs like SUN SDR or SDR console, which actually can use a Nvidia GPU for FFT)
on an old second generation I7 without any problem.
Your computer possibly uses memory sharing with video, in which case
installing more should reduce the symptoms.

Hi Philip,
WSJT-X knows nothing about GPUs and makes no use of one. I run
PSKreporter alongside WSJT-X all the time, with no noticeable effect on
decoding performance.

in pskreporter, then decode performance returns to normal. I suspect
some type of GPU issue as the night shadow in pskreporter uses WebGL to
