[Bug] [Scaleforms] 3D Scaleforms flickering/jittering on position update / frame rendering

[manups4e]

Summary

When drawing 3D Scaleforms in world space, the elements experience noticeable flickering and rapid z-fighting or positional jitter. Instead of rendering smoothly at fixed 3D coordinates relative to the screen/camera transform, the scaleform panels rapidly flash or drop frames during rendering tick cycles.

Possible Causes

• Tick Loop Synchronization: The native 3D render call is not being invoked on every single frame, or execution order relative to camera update causes frame misalignment.
• Double Drawing / State Collisions: Multiple tick handlers or calls attempting to draw/update scaleform transforms simultaneously.
• Depth / Render State Conflict: Missing depth buffer handling or matrix recalculation lag on frame update.

Steps to Reproduce

I provided a reproduction script with a very basic scaleform, you will notice that when commenting the 3D rendering code and using the 2D full screen rendering, the scaleform is steady and perfectly working while on 3D rendering.. some flickering on spot happens.

Expected Behavior

3D Scaleforms should render smoothly at their designated 3D world coordinates without flickering, flashing, or frame-skipping between tick calls.

Actual Behavior

The scaleform elements flicker continuously on the screen during positional drawing, likely due to execution order in the tick loop, missing/delayed per-frame redraw calls (DrawScaleformMovie3d / matrix transforms), or synchronization issues between the script tick and game render thread.

Thanks for the detailed report! I'm going to take a look at this.

[dalekenium-cfx]

I'm actually not seeing the same flickering with this square (or the hex) that you show in the video:

3dscaleformexample.mp4

Can you share you graphics settings, maybe?

[manups4e]

Sure! Thanks for your quick response!
my settings are

• No raytracing
• borderless window
• no nvidia reflex
• no frame scaling
• no frame generator
• TAA anti aliasing
• usual settings on Ultra / High
• ambient occlusion on SSDO

i'd send all the screenshots but my game is in italian.. hard to see you understanding it :3

i'm on build 104 clientside and 105 serverside and it still happens.. now.. your video shows the problem as my scaleform well trained eye can see it.. but the rotating cube masks the effect so i changed the script using a steady scaleform from the game itself.. try this:

wolfram.zip

I used the classic mp_mission_name_freemode scaleform and this is the result

[dalekenium-cfx]

Using the new resource you just provided, the flickering stops for me if I turn off anti-aliasing altogether. Can you confirm it does the same for you?

[manups4e]

Yes i confirm.. i tried changing everything besides AA, Resolution and FullScreen mode.. i really couldn't think that AA was the culprit! (there's still a lot that i need to learn :3 )

Edit: disabling AA and re-enabling it.. the flickering doesn't occur again, the scaleform remains perfectly still.
But if present, disabling AA fixes it

[dalekenium-cfx]

It is specifically TAA that causes the flickering, FXAA does not cause it for me. That's really weird. I'll continue to investigate and see if I can find anything to fix on our end.

[wolfram-cfx]

Was indeed caused by TAA. I can no longer reproduce it locally after my fix.

[manups4e]

Awesome! Thanks!

[Gogsi]

A fix for this bug has been implemented and is available in the August 4 patch. Please try again and let us know if the issue persists. Thanks for your help!

[manups4e]

Ok so i confirm the fix is working perfectly!

• I only report this minor issue with objects / surfaces in front of the scaleform in TAA still flickering a bit (ped hair and the metal bar on the center), but i suspect that nothing can be done about it probably

[Gogsi]

I think that's just TAA artifacts around thin objects

[manups4e]

Yeah I agree.. the main bug is fixed nonetheless 😊
