- Time for another strange one from the deep dungeons at bug HQ.
-
- I'm using a pri 21 task to cycle my colours on my screen. (it was
- originally based on CYCVB but then that went down down the drain...).
- My problem is that when I do an OpenScreenTags I get this flash on the
- top of the screen like the title-bar is trying to break through. Now this
- only lasts for about a frame or two and I'm trying to use
- SA_ShowTitle, SA_ScreenQuiet & SA_ScreenBehind to avoid it.
- As usual with my absurd problems,
- if I switch off my Colour Cycling task it won't happen.
- My cycling task is NOT cycling the screen that's being opened, but it is
- cycling the screen that's being displayed.
- And yes, I don't actually think it's the title-bar because the flash
- seems to come far outside the set overscan region,- but it varies a bit.
-
- The flashing white line I get one the top of the screen is Related to
- my OpenScreen call. If I don't open the screen it doesn't flash.
- If I don't open the screen I won't get the job done :-(
-
- Anyone have any suggestions ?
