Blender Version
Broken: version: 4.3.0 Alpha, branch: main, commit date: 2024-08-22 21:37, hash: d5e591b3dc8c

Short description of error
I don't know if this qualifies as a bug. I know forward compatiblity is never guaranteed, but I just find this one pretty harsh because normally the forward compatibility break is not this bad.

When 4.3 preferences are loaded in 4.2, certain UI strings fail to draw. Below is just one example.

Repro steps:

Save your user prefs with 4.3
Rename your 4.3 folder to 4.2
Open 4.2
Bunch of text should be missing.

Use case:
I have my blender config files symlinked from one place to all blender versions, since I jump between so many different versions all the time for reasons like testing backwards compatibility of my add-ons, or opening old project files to steal tech, or create learning material about them, stuff like that.

I can confirm this issue. I will also mark as high severity as it's a recent regression from developers are free to lower this.

There is a desire for some for of foward compatability between LTS and newer versions of Blender, but I'm not sure how important this is for user preferences compared to something like models.

I decided to bisect this

A user preference saved in Main from yesterday (24th of August 2024) does not have issues in builds 108b71047a and newer.

I doubtful this commit will be backported to 4.2, but it's useful to know what caused it for anyone that might try to add forward compatability for this change to 4.2

I think the only thing we'd need in 4.2 is just a check to see if UI_style_get()->widgetlabel.points is zero. And if so then just set it to the default, so UI_DEFAULT_TEXT_POINTS or 11. I think.
