paint.net 4.3: Footnote of IndirectUI control in FileType shows artifacts after scrolling

[midora]

Sorry no attachment because the merge of the account exceeded the limit (and I have no idea why I'm not able to delete old stuff).

I'm using a 125% scaling.

Yeah there's something weird with the rendering that I'm currently trying to nail down

 

These are the PdnLabel control, and Settings also uses it but doesn't have this garbly result, so I don't know what the difference is just yet

 

[Rick Brewster]

Okay I have a fix for this.

 

I think this is actually a rendering bug in DirectWrite. My fix is to first render into a bitmap and then draw the bitmap w/ clipping, as opposed to drawing the text w/ clipping.

 

This was affecting links, too. (PdnLinkLabel)

[midora]

I remember that I have seen the issue in PdnLinkLabel too but forgot to report it.

 

Maybe the issue is related to the padding of the strings at the beginning or end (i.e. via StringFormat).

I did fix up some layout code regarding padding, but the old code was just accidentally doing the right thing but in a dumb way. So, I really don't know. Setting Padding to 0 didn't fix things.

I meant the padding via TextFormatFlags (LeftAndRightPadding, NoPadding) and not the Padding property. But I have no idea if DirectDraw provides similar functionality.
