With GTK 4, tooltips are sometimes broken. They usually work... except when they don't. Test by hovering over a link to a bug in this Bugzilla instance (e.g. the GTK 4 bug in the "Blocks" field up above). When they don't work, they don't work for any link. When they do work,t hey work for all links.
Interestingly enough, when a tooltip fails, this happens: ``` (MiniBrowser:17): Gdk-CRITICAL **: 05:04:13.942: OPENGL: Source: API Type: Error Severity: High Message: GL_INVALID_OPERATION in glGetFramebufferAttachmentParameteriv(invalid pname GL_FRAMEBUFFER_ATTACHMENT_RED_SIZE) (MiniBrowser:17): Gdk-CRITICAL **: 05:04:13.942: OPENGL: Source: API Type: Error Severity: High Message: GL_INVALID_FRAMEBUFFER_OPERATION in glClear(incomplete framebuffer) (MiniBrowser:17): Gdk-CRITICAL **: 05:04:13.942: OPENGL: Source: API Type: Error Severity: High Message: GL_INVALID_FRAMEBUFFER_OPERATION in glDrawArrays (MiniBrowser:17): Gdk-CRITICAL **: 05:04:13.942: OPENGL: Source: API Type: Error Severity: High Message: GL_INVALID_FRAMEBUFFER_OPERATION in glDrawArrays (MiniBrowser:17): Gdk-CRITICAL **: 05:04:13.942: OPENGL: Source: API Type: Error Severity: High Message: GL_INVALID_FRAMEBUFFER_OPERATION in glDrawArrays ```
OK, I'm running with G_DEBUG=fatal-criticals now to try to get a backtrace, but sadly the tooltips that were so broken for me yesterday are working just fine today. Let's hope I manage to catch it.
Ok, it's GTK. https://gitlab.gnome.org/GNOME/gtk/-/issues/5258

Let's hope I manage to catch it. I had to give up on this due to https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1055. A fix for that issue was just released yesterday, but hasn't hit freedesktop-sdk yet.
I think this got mysteriously fixed at some point in the past year.
