Window frozen after sleep

[Chadnaut]

Sometimes AM appears frozen after waking PC from sleep.

• Master build (533), Window Mode
• A few hours up-time (developing layouts, ie: many reload events)
• Close laptop for the night, putting it into a sleep state
• Open laptop 7 hours later
• AM is frozen on a single frame of the screensaver
• Despite pressing all inputs, the single frame persists

However

• Console logs show AM is still responding
• Displays get loaded, focus events reported, games can be launched
• It's only the window surface that is not getting redrawn

I'm sure I've experienced something similar with previous builds. This time I dug around a bit more instead of just restarting. Might be a tricky one to reproduce.

Yes, it may be tricky, one try per night. I'm unable to reproduce with short sleep periods.

• Does it happen also on layouts, or just on the screensaver?
• ~Can you open the settings menu?~ nvm
• ~Does pressing reload helps in any way?~ nvm
• Have you tried resizing the window? It reinitializes the surface.
• Is audio still working?

[Chadnaut]

• When the laptop was closed my layout was running, I'm not sure how the screensaver started during sleep... will disable screensaver for future tests.
• Possibly, but the window never redraws so it's hard to tell. AM responds to inputs (next display, etc)
• The reload occurs, logs show as much, but the window never redraws
• Resize just stretches the frozen texture to fit
• Did not test audio, will test if/when this re-occurs

I left my pc sleeping overnight with AM+ running, but it did not freeze. Will keep trying.

[Chadnaut]

PC slept a few more times with AM running (screensaver disabled):

• Woke to working layout, a few minutes later crashed (likely during focus change)
• Woke to working layout, worked fine

Results appear to be random, put this on the backlog and revisit when reliably reproducible...

[Chadnaut]

• Woke to frozen layout today
• No abnormal GPU/CPU/memory behavior
• Audio still plays, and changes correctly with game selection
• Blindly navigating to Settings > General > Window Mode and changing it (in this case I chose borderless) un-freezes the display

So there's another clue - re-initializing the window restores redraw.

[oomek]

That's a very helpful clue. We are reinitializing audio device due to sfml bug, so Lets reinitialize window also on resume

[Chadnaut]

Possibly related: offset window content after returning from game. It may be a nVidia Quadro T1000 related issue, but no other window suffers from this. I'll probably have to sort this out (at a later time) since I have the hardware to reproduce it, and it occurs randomly... Moving the window fixes the offset.

[oomek]

Again, I've never had this issue. It must be a Quadro thing. Do I have a green light to push the 3.2.0 label and start constructing the changelog?

[Chadnaut]

All good. Leave this issue with me and I'll have a play sometime in future.
