Upon building today’s git main@1229d635… the tooltip issue with the GTK4 NGL renderer is resolved.
I suspect also the popover/dialog distortion issues noted over the course of this thread may too be resolved/improved, but as noted several times previously, they became very rare and difficult to reproduce with recent GTK/Adwaita releases.
I’ll wait to mark this SOLVED until egl-wayland2 is officially tagged & packaged for my distro, and the temporary-fix env var is no longer required. Hopefully in the 580 driver.
I will, however, update the tracking thread now. Sweet!
Thanks again to @kbrenneman for picking this up. 👍
