StaticLayout inside AppWidget ListView shows invisible text if over 50 lines

Question

I have an AppWidget RemoteView with a ListView that holds one child - ImageView with custom font text.

Here is my code:

Typeface tf = Typeface.createFromAsset(mContext.getAssets(),"fonts/myfont.ttf");

TextPaint textPaint = new TextPaint(TextPaint.ANTI_ALIAS_FLAG);
textPaint.setTypeface(tf);
textPaint.setStyle(Paint.Style.FILL);
textPaint.setColor(mycolor);
textPaint.setTextSize(px);

StaticLayout staticLayout = new StaticLayout(textString, textPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0.0f, false);

Bitmap bitmap = Bitmap.createBitmap(width, staticLayout.getHeight(), Bitmap.Config.ARGB_8888);

Canvas canvas = new Canvas(bitmap);
staticLayout.draw(canvas);

rv.setImageViewBitmap(R.id.imageViewText, bitmap);

It works correctly. But, every time the text is long enough to exceed 50 / 60 lines, it shows as empty, but i can scroll the listview (so the staticLayout is not empty, because the bitmap's height is not 0).

Another important thing is the following behavior: When i start drag the widget, the text appears. Immediately after i drop it, the text disappears again.

What can cause that kind of behavior? Maybe someone faced similar problem can help.

EDIT:

I tried to save the bitmap as png to the cache directory, then set the image via setImageViewUri method, but the result is the same. Transparent image with the right dimensions, and when drag and drop - its visible.
