RC Window flicker in P3D v5

[bobrbend 28]

Don't know if anyone else has had this issue, but about an hour into a flight, my RC SimConnect widow will begin to flicker. Eventually, on a longer flight, it will disappear altogether.

This has happened in both PMDG and Aerosoft aircraft, so they are not the culprit.

Any ideas?

Thanks..

Definitely not a RC issue either. Probably graphics. Do you have VSync enabled?

I have this issue as well.  Others have posted in the P3D forum about it, and it seems to happen with all Simconnect windows, so sounds like a glitch in v5.  My issue also causes a stutter every time the window flashes which is annoying, but luckily can close the window when not using.

In that case I'll move this topic to the P3D forum as it should attract more attention.

Vsync is off.

That's the problem then. Certainly with v4 I needed it on to prevent screen flickering. Can't imagine v5 is any different. Turn it on and that should fix it.

Thanks. I'll give it a shot.

[bobrbend 28]

No, sadly that didn't fix it.

In that case I suggest you post on the LM P3D forum. Make them aware of it and it should be fixed.

You might want to try to disable fullscreen optimizations (assume you are operating full screen):

See if that makes a difference.

Cheers, Rob.

Thanks, Rob, but not operating full screen.

I run in windowed mode and use Lua scripts via FSUIPC6 to display info, such as checklists and aircraft performance parameters like Radio Altitude, Mach#, etc. In P3Dv5 HF2 these displays suddenly begin to flash at a high rate -- multiple times per sec so that it is very difficult reading the display.  The flashing seems to start at random times, and the display window eventually disappears altogether. Restarting the Lua script will not re-display the window -- I have to restart the sim to do that.

This flashing problem also happens with information displayed on the Simconnect  "green bar" text window.

These very same Lua scripts and Simconnect message window/green bar displays work fine in P3Dv4.5 HF3.  I have posted about this on the LM forum in the Client Applications subforum but there has been no response of any kind to date.

This has been mentioned a number of times and I believe confirmed as a bug in V5. It's not a RC issue, it occurs whenever an application is using the "message text" feature. For me it's worse in the FSLabs A320 when activating the steering tiller - the FPS drop down rom 30+ into single digets. Goes away when the message text goes away. 

I've just disabled it in the P3D V5 settings and hope that 5.1 fixes it.

Thanks, Rob.  I do fly full screen, and this setting seems to have stopped the flashing on my setup.  Flew a 3 hr flight today, and no flahes at all.
