Andoid TLabels Have Lines on the Letters

[MikeMon 12]

Hi

 

I'm using Delphi 10.3.3.

 

I have a problem with TLabels on Android. There are horizontal or vertical lines on some letters in the TLabel. As you can see on the attached image, the "d", "y" and "A" of the label "Cloudy Apple Juice" have lines on them. So do the "h", "O", "u", "c" and "e" of the label "Fresh Orange Juice". I'm using Java JDK version 1.8.0_261. I don't know if this has anything to do with it, but lately I had to uninstall the JDK (of which I don't remember what the version was) and reinstall it (version 1.80._261).

 

Has anyone encountered this before?

 

And what is the default version installed by Delphi 10.3.3.

Does this happen on several different devices?

On all devices. Most of the times.

Anyone has any ideas?

This is an FMX issue, not related to Java. On mobile platforms FMX use own text rendering - glyphs are rasterized to (cached) bitmaps and these bitmaps are drawn to openGL textures. This code is not perfect and sometimes (depending on screen resolution and scaling) produce lines on bitmap edges.

Hi Alexander

 

Thank you for your input.

 

That's weird because this just started happening lately with the latest app we are developing.
