See screenshot (reproducible with the sample attached to https://www.grapecity.com/forums/winforms-edition/dpi-awareness-with-framewo_1): I think the “Close” symbol is dizzy at 125% scaling.
Do you agree, and would you fix it ;-)?

Hi Wolfgang,
Although I do not see much difference, I have escalated this to the development team and will let you know when we have an update.

Might depend on screen or graphics card. I had a similar issue with Firefox, where some texts appeared dizzy on my machine at work, but a screenshot of this screen looked OK.
Attached is a zoomed screenshot of the image attached to my initial post, which hopefully shows the issue: all three window symbols (minimize/maximize/close) are blurred.

Seems this was fixed in .532 - I found this in the changelog (and the icons don’t change any more):
-Changed RibbonForm glyphs from bitmaps to vectors. (C1WIN-24759)
Strange that this points to a different issue then the one you mentioned above (C1WIN-25364).
But it seems the close box is no longer antialised. Attached is a screenshot: upper part is the new ribbon at 100%/125%, lower part is windows explorer. If you zoom this screenshot, you will see that Windows Explorer has antialiased symbols. Are there plans to improve this?
Best regards

Hi Wolfgang,
As per the dev team, they have fixed this issue (C1WIN-25364) for the dpi aware application, but for non-dpi aware mode, it’s a limitation. Sorry for the inconvenience.
How to enable dpi aware mode: https://docs.microsoft.com/en-us/dotnet/desktop/winforms/high-dpi-support-in-windows-forms?view=netframeworkdesktop-4.8

Hi Avnish,
my initial sample (see first post) is a .NET 4.8 Framework application, and I think it has activated DPI awareness as described in your link ;-). So my comment about non-antialiased icons should be relevant here.
Best regards

Hi Avnish,
sorry for the late replay, I was on vacation.
I just noticed that the close box at 100% scaling was also not antialiased in my initial bugreport. So it is not a regression. Forget about my last comment ;-).
Best regards
Wolfgang
