My problem occure on hardware Advantech PCA-6176, Pentium-III, ChipSet
Intel440BX, Video ATI 3D Rage Pro Turbo
with QNX4.25C, Photon 1.14C and Pg.rage driver by 22-sep-2000 from Photon
Graphics Patch B.
In some not-root user programs RtTrend widget draw a lines. When lines
number is ( for example ) 19 ( for example ) the QNX4 System Time run at 80%
slovly then Real Time by my watch. If I stop draw RtTrend lines - QNX4
System Time run synchronously with my watch.
QNX4 System Time I check by ftime( struct timeb* ) function and by pwmclock
program.
With 20-th ot 18-th lines in RtTrend this effect is disappear.
I fix this problem when restore older Pg.rage driver version by 20-sep-1999.
How can RtTrend and Pg.rage drop QNX4 Real Time?
