Fuzzy window rendering on external 4K display

MacOS users can encouter visual bug with fuzzy lines appeared while connected to external 4K display https://www.forbes.com/sites/gordonkelly/2020/06/11/apple-macos-macbook-pro-google-chrome-display-problem/?sh=331ac27967b4. Same thing can happen with any of Electron applications or Chrome itself.

fuzzy lines

As a temporary workaround there is a possibility to disable Chromium GPU acceleration. To do this for Lens, you need to provide LENS_DISABLE_GPU=true env variable and relaunch app.

First, open .bash_profile file from your terminal

open -a TextEdit.app ~/.bash_profile

Then, add this line

export LENS_DISABLE_GPU=true

Save it and restart Lens.
