            | Title | Photon video error with infleet |  
            | Ref. No. | QNX.000006313 |  
            | Category(ies) | Video |  
            | Issue | We have the following: QNX 4.25B RTOS, Photon 1.13B microGUI windowing system, TCP/IP 4.25B, and Infleet 4.23 . 
 When we are in 1280x1024x8 mode AND Net.fd is running using an infleet device as a TTY, then we get vertical lines at the top of the screen.
 
 Any known problems with this combination?

            | Solution | The Infleet program is the problem.  Its debug info is writing directly to video memory which is messing things up.  Turn off the debug info will fix the problem. |  |
