Offset rendering and weird scaling on Linux #1120

Closed FauxFaux closed 6 years ago

FauxFaux commented 6 years ago

Since 339b0c658801e02f44d3be59c24d70560e762488 ("update glium and winit"), on Ubuntu Artful (16.10) with nvidia-384, things render off-centre and generally pretty messed up. Here's the image and file_navigator examples:

Note the huge black bar, as well as the text and hover highlight not being aligned.

I assume, based on the commit, that it's a problem with glium, but I'm as yet unable to pin it down. I only started playing with the graphics ecosystem a few hours ago.

Are you using wayland or xorg? I've had different linux rendering issues with each of them in glium. I don't know anything about the issue you're having, but more information on how to reproduce it could possibly help.

FauxFaux commented 6 years ago

I've tried Gnome and i3; both do the same. The binary nvidia driver means no wayland, as it's blacklisted due to being crap.

As it's graphics, I don't really have a good way to narrow it down; VMs probably won't help? Not a problem with the GPU as it happens in Windows. Maybe I should dig through the winit commits. :(

Darn, ok. I've been trying out different DPI settings on my linux machine with both wayland and xorg, but to no avail - I haven't found any configuration on my machine to caused this. I'm also running Ubuntu 16.10, but with Intel integrated graphics.

There's some progress on the gluim issue, which might be the same bug. Linked above, but clearer:
