Also I suppose I’ve found cause of a problem - NSStringDrawing caching methods rewrite by Fred. But I can’t understand what changes must be applied to ART backend to adopt new caching algorithm.

I am willing to help here if you could pinpoint the issue a bit down. Which commit are you talking about and in which situations does it show? The last time I used the art backend I did not see any issues. But I must confess I only checked with Ink.

I've made some screenshots with 0.27 version of GUI and Back (please see attachments) to illustrate some inconsistencies.

FontPreferencesPopUp and LocalizationPreferences-* illustrate NSPopUpButton text drawing.

WorkspaceMenu+HelpPanel illustrates - i guess - related problem: "Workspace" menu lacks border at the right side.

The other problem is with my custom HelpPanel that contains NSMatrix with index list (note selection offset).

Plus (it's hard to make screenshot of insertion point) in NXTHelpPanel's NSTextField insertion point drawn shifted at 20-30 pixels to the right until there's no entered text.

Now I'm using 0.25 version of GUI and Back - all works correcly.

Somewhere between 0.25 and 0.25.1 of GUI NSStringDrawing was massively changed by you. Do you know what is the cause of these inconsistencies?
