@ebassi #Gtk troubles. Following toshiocp.github.io/Gtk4-tutori…. Window of sec 5, messes up all my xterms windows: flickering by frantic scrolling, repeated lines and chars. Closing the gtk4-window restores all to normal. On debian-sid w/ mate. After successless search for help, I found a link "contact" on gtk.org leading nowhere. No user-group, no email-list. I did find your Mastodon ID and installed it. Now I dare to ask: "Where does a stuck newby go with gtk4?"

I recommend using Discourse: discourse.gnome.org/tag/gtk —which is linked on the website, on the project's GitLab, and in the project docs. We haven't used mailing lists in five years.

You'll have to specify which version of GTK you're using; which GPU; which GL/Vulkan driver; how you're launching the example; what kind of errors you're getting.

The toshiocp tutorial isn't written by GTK developers, so you may also want to ask the author.

dpkg says, it's 4.14.4+ds-8. lshw says it's GM107 (GeForce 940MX). The driver is the official nVidia driver. I'm using a clean debian-sid. the only thing tainting the kernel ist nvidia. I made an update (kernel 6.10.9) and rebooted the system, and tested again before writing my previsous message. lanch from terminal. Couldn't find contact info for that tutorial, but code is only 55 lines; you probl. would consider it simple.

Is it that the GPU is too old (as you seem to say) or that the driver is too old (as is said in that link)? as I said before, I had an update today so the driver shouldn't be old. nVidia still seems to support this GPU officially. is this "fake news" from nVidia? This also would mean, that not only Gtk is affected but also everything else, right? Shouldn't I have noticed the problem earlier? Sorry for the many questions.

Thanks for the clarification. I tried: GSK_RENDERER=gl. This slows down things noticeable, but doesn't make the problem go away. GDK_DISABLE=gles-api doesn't slow down things. At first it seemed to work, but after a minute or two, the problem showed again. Couldn't try the third suggestions, as I don't know how to tell the driver that, and can't think of anything looking for in a search engine.

sorry. I'm an old man. most of my windows are Xterm with Emacs. I'm a C-programmer (not GUI) and have never used any ID or other graphic environment for that. I have lots of windows open, while gnome will try to use all my screen for just one. Also, Gnome software tries to solve everything while Unix just one, being able to combine. For instance color management. The prime task is poorly solved, but there are tons of other bells and wistles.

I don’t understand why you feel the need to vent about stuff that happened nearly 15 years ago, about GTK3, an API breakage that took two years of work in the open to be complete; and about GTK2, a version that was EOL’d four years ago. The people “left behind” would have not contributed to the ecosystem anyway, as they clearly consider GTK a black box to consume instead of a project to contribute to.
