(GeForce RTX 4070) GTK application issue with NVIDIA GPU

When hovering over buttons in GTK, a tooltip is shown containing for example the label of the button. However, on Nvidia hardware, that tooltip is stretched and deformed. A GTK developer said this is an issue with the Nvidia driver, so I am reporting this here.

To reproduce:
Using a computer with Nvidia hardware (RTX 4070 for example) with no other GPU,

  1. Install any GTK app from Flathub, for example, Gnome Calculator.
  2. Hover the mouse pointer over any button with a tooltip, like the ‘Undo’ button.
  3. Try that a few times until it can be observed that the tooltip is stretched and deformed

Hardware: Intel i7-13700F/ Nvidia GeForce RTX 4070
Software: Any GTK app (e.g. Gnome Calculator) on Fedora Silverblue 39 with Nvidia driver version 535

Thank you for posting this @kdwkleung… it was on my todo this week.

I recorded a short screencast showing this issue, which I shared in the GTK issue you referenced.

  • Arch Linux | Kernel 6.6.4
  • Gnome-shell | Mutter 45.2
  • Wayland (gnome-shell --no-x11)
  • nVidia 545.29.06
  • GeForce GTX 1050 Ti

Indeed, this is affecting many apps currently, including several of core Gnome.

Hi @kdwkleung, would you please consider editing your thread subject line to be more concise?

Something like “GTK application tooltips are stretched/distorted”
