These fiddles illustrate the difference between CANVAS and WEBGL rendering:
WEBGL: https://jsfiddle.net/d5341sga/2/ CANVAS: https://jsfiddle.net/zbs9e7wL/2/
Note: the examples above are using Phaser 3.80.1
After extensive testing, there does seem to be some issue with kerning on WebGL.

Will have a closer look at this issue.
Thanks for bringing this to our attention.
This issue is resolved.
Fixed all kerning issues in WebGL bitmap text rendering. This includes adjustments to glyph positioning and spacing, ensuring accurate and visually pleasing text display across all WebGL contexts.

This will be part of the next release. If you get time to build and test it for yourself we would appreciate that.
