Glowed text on sign

With the new update, borders have been added in the text when applying on signs the glow ink sac, however in the many years that I have been playing Minecraft Bedrock / Pocket Edition from the distant 0.4 version, I had not seen what is more horrendous if it is possible to correct because that border in the text on the signs is horrible  this makes the game unplayable in devices with FHD + and lower resolution
