FIXING FONT PROBLEMS IN WINDOWS 10
The problem might very well be about CLEARTYPE, a technology meant to improve clarity of texts in LCD screens, but it seems to get in conflict with Rpgmaker games.
1-Go to Control Panel and click on Fonts,
2-Go to Adjust ClearType text,
3-Click on “Turn on ClearType” to deactivate it, then click Advance and choose a text format you want (keep in mind the one it was on before).
Your regular computer font might look a bit weird, but you can always go back to activating ClearType and choosing the old format.
