Thank you for the demo, I will check it soon.
Apparently you changed things. But I'm not happy. The texts now seem distorted and have uneven thickness:

Look for example at the two consecutive el's in Instellingen.
The cause for these problems is lack of anti-aliassing.
This text is rendered by Windows text API procedures.
Try to set the Quality of Font property to the ClearType, maybe it helps.
Maybe TsLabelFX could use GDI+ DrawString instead of GDI DrawText?

Stephane Senecal made an interesting remark.
Could you comment on that?
I will try to make it soon, but I'm not sure that GDI+ string drawing will work better than GDI with ClearType.
I will check it.

I will check it.
To clarify: the letter type (Trebuchet MS) and the quality of font (ClearType) cannot be the cause.
From what I tried, it seemed to output better result with DrawString from GDI+.
GDI+ does not use the same algorithm than GDI. Another weird thing from Microsoft.
More over, there is also DirectWrite / Direct2D, but those function use the GPU. I think it would be a little bit overkill.

In GDI+ text rendering is done completely in software. That makes it both slower but also different from GDI.
Thanks Stephane for your illuminating input
It crashes at startup with “Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item.”

Mmm, weird. It works fine on my end.
I've tried in a VM with Windows 10 too and it works there. weird.
You can stop investigate since it's just a sample project.

Sources I can send by PM, if needed.
The point of this exercise is: do the texts look OK when drawn in an angle.
Your test shows that they do look fine on my system. Having the same test with GDI would give the definitive answer.
PS. I do not have the reported problem. On my Windows 10 Pro system it works fine.
The text is drawn better under Win 10, but it looks same under Windows 7.
I'm searching the best solution now.
Stephane Senecal, I need to find why it was crashed on your side. This error is repeatable still?
It's the anti-virus (Windows Defender) that prevent execution.
From what i have researched, it seems like the anti-virus thinks it's a ransomware.
I hope it's a false positive.

It is: my virus checker does not find a problem. I had a false positive with WIndows Defender before. That virus checker sucks.

Did you change the implementation? Because with version 4.17 I do not see any difference.
