As usual while waiting for the next release - don't forget to check the nightly builds in the forum.
Try right clicking on the codeblocks.exe file and looking at Compatibility tab.I suggest trying the "Override High DPI"; this is just a guess.The thread implied the adding of an manifest file or the editing of a manifest file.Edit: The fix was adding an external management file for Windows XP; I do not see a fix for Windows 10; but, I suggest trying the Compatibility setting above and see if it work. I am on Windows 10 32 bit; but, the fonts has looked blurry to me for years on this computer; so, I can not test any thing. Tim S.
