[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.

[Baughn]

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.

[lvl19]

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.

I seem to always get flickering when I try to switch between monitors.
Log is attached, but it does not fully catch what's happening. Terminal from which I launched Factorio via

I can only reproduce this with native Wayland rendering. When set to X11 it's fine. Since I don't have any issues with the X11 backend I'm gonna go back to that for the moment.

[raiguard]

I have a feeling that this has the same root cause as the Sway flickering issue I showed in FFF 408, which I still have not figured out how to fix.

I have been able to reproduce some weird jittering on plasma, but nothing as bad as you have shown in your videos.

[lvl19]

I made a few more observations which may or may not be helpful. (X11+i3)
First of all, I can reproduce the issue on a single monitor, by having factorio fullscreen with another window on the same workspace, and forcing factorio to a normal window. Then it starts to flicker between window and fullscreen.
Secondly, every cycle of going fullscreen and windowed generates more events than it consumes. After moving factorio to an empty workspace it recovers after a while, but if I let it flicker for longer before moving it, the recovery takes proportionally longer.
Third and perhaps the most important: the problem goes away completely, if I uncheck "Fullscreen" in the graphics options. If I do that, I can still tell i3 to place factorio in a borderless fullscreen window. When I move that window to a different workspace, it stays in borderless fullscreen. Contrast to when I have the "Fullscreen" option enabled, the game briefly drops out of fullscreen when moved to another workspace, before going back to fullscreen.

As for the SDL event logs, I'm not sure if I can set environment variables with steam version, only arguments. I might need the standalone version for that.

You can set launch options in Steam to

Log.
1. I launch factorio. The game is opened fullscreen on 1st monitor.
2. Initiate flickering by exiting fullscreen. i3 should resize the window to occupy the right half of the screen, with some gaps left over for borders and such.
3. Around SDL timestamp 4700 I request the window to be moved to an empty workspace on my 2nd monitor. I use key combination win+shift+2 to move the window. win (scancode 227) and shift (scancode 225) are visible in the log, but the number key is not. It takes me a couple of tries, because the game is only in focus ~half of the time, so the timing isn't very precise.
4. Flickering eventually stops and I close the window.

[Baughn]

Let's see...

- All my screens are at the same KDE-set scale, but they're all 125%, not 100%.
- I noticed this time that the menu bar on the leftmost monitor is also jittering up and down, though my guess is this is because a fullscreen window is jittering between monitors.
- Here's an event log:

The rest of this is just more of the same, at progressively higher timestamps.

- If I set the KDE scale to 100% on all three monitors, then... nothing changes; the problem is still there.

Thanks for the reports, this has been fixed for the next release.
