I have 5 process RTP application which uses Photon as GUI interface. I
experience terrible situation any time grapics process updates screen. The
sequence of calls in gui process is like unrealizeWidget, destroyWidget,
createWidget, realizeWidget. Any time these sequnce of calls looks like
threads of another processes are blocked for about 1 second. I tried to
change Photon priority as well as io-graphics driver priority below the
priority of running processes. It does not help.
Hardware configuration: 486 100Mhz.
QNX 6.0 B, svga driver.
Gurus please advice.
