High DPI support on ToolStrip in .Net 5

[AngeloCresta]

In .Net 5 it seems that there is a regression in toolstrips with High DPI enabled (Per Monitor v2) compared to .Net Framework 4.7.2, check the image below where the 2 apps are running side by side (monitor with scale at 150%).
It's by design?

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

Shouldn't this go to https://github.com/dotnet/winforms? Don't close the issue; I think a member can simply transfer it.

Are they equal at 100% dpi? If no, then it's ok.

[AngeloCresta]

I don't think so when your app is set Per Monitor-DPI aware (v2) and the behavior is btw different from the. Net fw 4.7.2...

[kirsan31]

You have 2 options here:

• Set dpi to 100% and compare. If they are not equal - see my previous post. If they are equal - see below.
• Provide a repro.

[AngeloCresta]

Yes, they're equal.
Same size at 100%.

Seems other one is a copy of this. Did you try on .NET 4.8? HDPI feature changes were spanned across releases starting from .NET 4.7.* and would need to opt-in if you are not targeting latest. I believe Net 5.0 will match with .NET 4.8.

[AngeloCresta]

Tested with .net fw 4.8 (light) e .Net 5.0 (dark) with the same size at 100%, at 150% the result is still different:
the strips are just "colored" via renderer manger, without overriding drawing methods.

and there's the same behaviour on status strip:
