Could you please create an issue on GitHub? Please also provide your system specs. Is your graphics drivers up to date by the way?
It was merged, but it seems like not a complete fix. My main problem now is that I am unable to reproduce your issue in the 1.12.1 beta on Windows 10! I never get that socket error and the request is always successful…
I have a fix with the missing memset on the proxy url in this commit:

Quick Update:
The GUI manipulations as well as editor animations (Bottom right loading bar) smooth themselves out (Not so much when it comes to the animation. Its noticeably smoother, but not by much) after alt tabbing to another program or Ctrl + Scrolling Up/Down.
I dont have many programs open that could affect the performance of the editor, I just have the 2 versions of the editors; 1.12.0 & 1.12.1 Beta and a web browser (Microsoft Edge)
The only thing noteworthy is that RAM usage of the editors dropped from 1.4GB to 1.088GB and Defold 1.12.0 isnt being shown in Task Manager, despite running
There was another update, after the Stable 1.12.1 release in the steam version that fixed this issue for me.
GUI Manipulation in the Editor main window, as well as animations in the editor are now smooth and responsive. Thank you everyone! (Even though this clip is 10MB, I cannot upload it here)
The hotfix we did for 1.12.1 was only related to android builds, not any editor changes.

I always recommend to check if you are using the latest intel GPU driver using the official Intel’s tool:
Sometimes it finds updates even when the other tools say it’s the latest version.
It happened before:

Not the one that dropped today, the one that dropped the same day 1.12.1 (Yesterday, 5th Feb 2026). As soon as I installed and updated 1.12.1 from 1.12.0, I was greeted with another updated and I did download, install and restarted the editor.
Haven’t experienced the issue since.
Yeah, I did that for Github Issue #10528.
The IGPU I use hasn’t gotten an update since 2020, because it was discontinued.
