Am gasit ceva:"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."
Multumesc mult! Am incrercat prima varianta si acum se vede bine.
Cica si asta ar merita incercata: pui asta in notepad si-l salvezi cu extensia ".bat":
@set "__COMPAT_LAYER=~ HIGHDPIAWARE" & start "" /max "CbLauncher.exe"
