By text I mean Editor text.

[Miguel Gimenez]

Starting with wx3.1.6 many controls, wxMenu among them, manage image scaling internally (see wxBitmapBundle). I think images are being scaled twice, but I do not use HiDPI so I can not test.

[Miguel Gimenez]

Adapted Spell Checker to use wxBitmapBundle, [r12861].
More changes will follow.

[Miguel Gimenez]

Added cbArtProvider::CreateBitmapBundle(), [r12865].

I will pause work on the ticket until mid september. Meanwhile, I will release ownership just in case somebody wants to work on it.

AnnoyingDialog fixed in [r12884], see CB_05.jpg in the original post for reference.

[Mehdi Chinoune]

Not fixed here!

Notebook icon sizes fixed in [r12887], see CB_01.jpg in the original post for reference.

[Miguel Gimenez]

Fixed menu, button and toolbar sizes in [r12889].

Font size can be corrected using Settings->Editor. I will close this ticket as fixed, if there is another problem with HiDPI please open a new one for better tracking.

[Mehdi Chinoune]

I am still considering the font size as an issueز
I have to increase font size to 36 (~= 14*2.5) to get the same size as the previous 14
the code hints look so big (see attachement CB_05), It should look like CB_08.

Thanks, waiting for the next nightly build to test your changes.

[Miguel Gimenez]

The AnnoyingDialog looks fine here (see attachment), although I am using wx3.2.1 and my test scale factor is 1.75 (I do not have a HiDPI monitor, and debugging this is a pain).

Regarding the font, I will follow ticket [#1302]. Meanwhile, you can try changing the font rendering technology: Go to Settings -> Editor -> General settings -> Other editor settings and select Technology = DirectWrite.

[Mehdi Chinoune]

Changing Font rendering technology to DirectWrite fixes the font issue.
Why Is it not enabled by default? Is Windows XP still supported?

But there are many remaining big icons, I will report bug about them

[Miguel Gimenez]

I am currently working on ThreadSearch, next will be DoxyBlocks, but I know there are more. If you make a list in a separate ticket it will be easier for me.

I progress slowly because, as I said, I do not have a HiDPI monitor so testing is a pain.
