Hi all,

After migrating a project from TIA Portal V17 to V19, I was required to upgrade the firmware of my TP900 Comfort Panel from V15.0.0.0 to V17.0.0.0. Following this upgrade, I noticed a significant font rendering issue on the physical HMI screen.

The issue: All text appears noticeably thinner and less bold than expected, which greatly affects readability. Strangely, in the TIA Portal V19 editor, the screen layout and fonts display correctly with the intended bold styling.

Has anyone encountered this issue?
How can I resolve this font rendering inconsistency between the editor and the physical panel?

Thanks in advance for your help.
