[raiguard][2.0.7] Massive flickering when switching monitors

[Baughn]

Factorio reliably starts up on the left-most display on my setup, by default. When I try to move it to screen 2 (i.e. the central, primary display)...

This happens: https://brage.info/75122881937__C9B04B3 ... 3A04DD.mov

The monitor change does actually take effect correctly, upon restart, but I have to SIGQUIT the game to make it exit.

Fortunately I don't have epilepsy.

I think this might only be an issue on Wayland. (However, the game is incredibly laggy (and blurry) on X11.)

[Baughn]

Console output. I've changed no settings from the default besides 'preferred video driver'.

Though I doubt this is relevant, the game still has the long-standing bug that it shows the primary display as display #3 (but starts up on #1 by default anyway?), while actually the KDE desktop setting is #2.

Do your displays have different UI scales?

What I think might be happening is that the window switches its scale to that of your primary monitor, which causes a resize, which then causes the centerpoint to move back to the left monitor and it resizes, which pushes it back to the primary monitor, then it resizes... and so on.

Something similar happened to me on X11+i3, although i haven't been able to reproduce it. The game was rapidly flickering between fullscreen and ~half screen size. While this was happening the game was stuck in the initial loading screen, "generating bitmaps" or something like that. I thought it was caused by i3 or a faulty mod, but there might be something here.

[raiguard]

Please add

Code: Select all

SDL_EVENT_LOGGING=1

to the launch command for Factorio, reproduce the problem, and upload the log. That may give me some insight into what is going on.

[lvl19]

Managed to reproduce on X11+i3. The key was to have something already open on the other screen. When I move factorio to a screen with another window open, i3 attempts to automatically resize the window to fit both on the screen. Most other programs would simply remain fullscreen after moving.

Steps in the attached video:
1. Steam open on screen 1.
2. Launch factorio.
3. Move factorio to screen 2. (Screen 2 not visible on recording)
4. Move factorio back to screen 1. Flickering starts.
5. Move factorio to another (empty) workspace on the same monitor.
6. Factorio recovers after a while.

WOW this describes perfectly what I just experienced with 2.0.8 on Wayland + Gnome, two monitors. Primary monitor at 2160p (ui scale 2×) and the other one at 1080p (ui scale 1×). Will try to reproduce and get a log. Although it's possible the game was set to use X11 while that happened. Will investigate.
