This issue is still present with nVidia 575.64 New Feature Branch driver.
Issue Summary:
‣ The effort by an nVidia developer to address this known issue was abandoned almost a year ago.
‣ GTK4 switched to the Vulkan backend as default in the meanwhile, leaving this NGL issue less prominent.
‣ Modern GTK 4.18 and Awaita 48 widget changes have mostly mitigated the areas where this bug manifested.
If an nVidia mod/dev would be so kind to supply the internal bug tracking number, I can add it to the tracker thread.
