Hello @Stephan_B
BUG 1
I found a bug related to method OnPrefabInstanceUpdate inside TMPro_UGUI_Private when asset was reimported and object was detroyed because of this process(unity 2019.3.0f1).
In code below the line “if (go == this.gameObject)” will return null because the “this” is null.
To fix the problem you should change it to “if (this != null && go == this.gameObject)”
/// <summary>
void OnPrefabInstanceUpdate(GameObject go)
{
if (go == this.gameObject) // this line will return null on asset reimport because this == null
{
TMP_SubMeshUI[] subTextObjects = GetComponentsInChildren<TMP_SubMeshUI>();
if (subTextObjects.Length > 0)
{
for (int i = 0; i < subTextObjects.Length; i++)
m_subTextObjects[i + 1] = subTextObjects[i];
}
}
}
BUG 2
Another bug is related to TextMeshProUGUI line 370.
Sometimes this method was called before m_canvasRenderer != null. to fix the problem we can change m_canvasRenderer to property canvasRenderer or check
if (m_canvasRenderer == null) m_canvasRenderer = GetComponent();
public override void Cull(Rect clipRect, bool validRect)
{
//Debug.Log("***** Cull (" + clipRect + ", " + validRect + ") Cull: " + m_canvasRenderer.cull + " *****");
if (validRect)
{
m_canvasRenderer.cull = false; //This line, sometimes contains m_canvasRenderer == null in editor
CanvasUpdateRegistry.RegisterCanvasElementForGraphicRebuild(this);
return;
}
base.Cull(clipRect, validRect);
}
