Assertion occurred after Laptop Suspend

[will824]

Experiencing an issue when the computer comes back to sleep.

Important points to note:

• XPS 15 9500 2020 with Windows 10 and latest updates
• Multimonitor mode through USB Hub through VGA and HDMI.
• Issue happens sometimes when the computer comes back from a long standby.
• ConEmu shows the error but the application does not close and in fact works correctly

ConEmu information:

Could you update to the latest version, run ConEmu with the -log switch, and reproduce the issue? I need the Log Files with repro + new dumps.

I'm having the same problem. My laptop's display is 4K. External display is 1080p. Can't reproduce when ConEmu minimized (in the taskbar). It seems the error only occurs when ConEmu runs in the background.

The log and dumps are here.

Thanks, I will check that

I see the same issue (assertion after hibernate wakeup). It only happens sometimes for me. I have ConEmu maximized on my primary monitor (4K with scaling enabled maybe related to scaling?) and have a secondary monitor attached as well.

Windows 10 Version 10.0.19042 Build 19042 ConEmu build 220418 64

Just hit this error for the first time when I left Inkscape running, hibernated my laptop, and then plugged into a multiple monitor setup and unhibernated the laptop.
