Hi - I see that there has been some conversation here already about tooltip distortion on GNOME/GTK applications, and that it seems that interest in pursuing a fix may have been muted because GTK has changed to Vulkan by default, which makes the issue moot? [image] GNOME/GTK…

this is fully fixed with drivers 590 and newer using egl-wayland2

Cool. Thanks! Built and installed egl-wayland2 from git main. COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME nautilus 1034 tekstryder mem REG 259,2 84512 1870808 /usr/lib/libnvidia-egl-wayland2.so.1.0.0 brave 1351 tekstryder mem REG 259,2 84512 1870808 /usr/lib/l…

It can coexist, but note that there’s also a driver bug where the platform library order got flipped around. It went unnoticed before since there was only ever one library to match, but with two of them now, our current drivers will use 10_nvidia_wayland.json before 09_nvidia_wayland2.json. We shou…

Thanks for the additional info. I hadn’t noticed any issues, after a day of use. vkcube is segfaulting as of most recent driver, but I’ll crack a separate thread for that with a backtrace. Unrelated. [image] kbrenneman: If you prefer to keep /usr/lib clean I packaged it for my distro, so pa…

so basically after installing egl-wayland2, and doing the work to make the driver use it, you didn’t notice any more distortion in the tooltips, is that correct?

No. This had zero effect on the tooltips. Nor did I expect any. Happy to continue further discussion over on the relevant GTK thread to keep noise down here. This one’s a newer duplicate anyhow.

thank you for filing the internal bug

Dang it. I wish I could say it’s a new one for me, but I did exactly the same thing with egl-x11. I could’ve sworn I tested that and got it right this time, but apparently not. Anyway, I fixed the y-invert flag, so it should be right side up now.

Ha! Well not to take sides, but top left origin makes more sense to me. After rebuilding and re-applying the env var… …the tooltips are displaying correctly with the NGL backend. Wow! Thank you.

[image] kbrenneman: Dang it. I was so quick to celebrate uncorrrupted tooltips I failed to notice some major breakage elsewhere. GBM platform is no longer initializing with the env var set: $ eglinfo -B GBM platform: eglinfo: eglInitialize failed Wayland platform: EGL API version: 1.5 EGL …

Speaking of flipped around, I added…

__EGL_EXTERNAL_PLATFORM_CONFIG_FILENAMES=/usr/share/egl/egl_external_platform.d/09_nvidia_wayland2.json

…to my environment, and after restarting, all GTK4 applications are rendered upside-down! 😛

That’s a new one. Need to brush up on my headstands.
