Archicad 26 - 2D Antialiasing - Possible BUG

[henryL]

Hi, 

i usually work on a 27" inch 4k display at 150% windows scaling and with 2D antialiasing turned off. Half the lines are thick and blurry.  

Scaling at 100% is a bit better but you can still see the the problem.

No problem at all with Archicad 25.

Contacted AC support about this and so far no reply apart from an auto email saying they had responded and if I didn't reply they would consider the matter closed

Even in the auto response it says they have a "copy of the response below" but there is no response...

I replied saying there has been no response and so far only silence

AC Support where are you on this issue please?

Unfortunately AC26 is unusable with the poor line rendering as it makes my eyes and head ache

Please could you let us know what is being done to fix this

I am also experiencing screen quality problems. Even the input tab window shows the numbers thicker and distorted. When I zoom small text of 2mm (model size) the text gets 100% distorted.

Lines show thicker and not crisp at all. Everything compared to 25.

Everyone, please make sure you contact your local Archicad support and complain about this display issue.

I have done this and asked them to pass the message on to Graphisoft HQ in Hungary.

I think only with people complaining through official channels, might this problem be looked into and hopefully fixed.

Otherwise I feel this problem will just be over looked.

The screen display is not a critical bug in that id does not crash Archicad or affect work output.

But it is rather annoying.

A bigger issue if the fonts actually moving (depends on the font style) in 26 as mentioned in other posts.

This link will hopefully let you contact your local support.

Just seen the release notes of Archicad 26 Hotfix 4000:

• DEF-9235 DOCUMENT: Dimensions from GDL objects were lost from sections during Archicad 24 to Archicad 25 conversion.

I am not sure whether the user interface fixes are related to the rendering problem.

JUST TO CONFIRM THE FIX AT THE REGISTRY NOTE IN THE POST:

https://community.Graphisoft.com/t5/Document-Visualize-forum/Fonts-displaying-incorrectly-after-movi...

FIXED THE PROBLEM WITH THE LINES. THE LEGACY RENDERING ENGINE WORKS CORRECTLY IN Archicad 26 COMPARED TO THE NEW ONE WHICH FOR SURE NEEDS TO BE FIXED.

[Botonis]

The update 4004 for 26 was just released but unfortuanately it does not fix the antialiasing problem.

Text is moving and distorted when zooming. Lines are thicker and sluggish.....

Pitty................

The comparison was made after deleting the registry fix that enabled the legacy rendering.

I will have to renable it.....

[JohnJay]

Installed the AC26 update but lines still look thick and blurry

Received an email from support a few weeks ago saying they'd be in touch with an update but only silence so far

[Botonis]

They have officially recognized the bug after the preview hotfix was released. It is not mentioned whether it will be included in the final hotfix or a future one....

Hello.

Have any of you tried to install the update 3? Has the antialiasing problem been resolved?

thanks 

[Botonis]

It feels like it is fixed. The lines are not thick any more and the fonts are shown correctly.

Install the latest one because there several other things fixed.

[JohnJay]

It's the same as before here

Irregular line thickness in AC26.  If I use the registry hack then it all looks as expected (like AC25 and earlier)

Update 5004 installed
