Unhandled exception: Stack Empty

[NickyD]

I physically reconfigured my monitors recently. Since I reconfigured them, I've been having a very odd problem. NT works completely fine on monitors 1 & 2. However, on monitor 3 only, if I click the "indicators" button on a chart that resides on that monitor, NT freezes and eventually throws this exception.

Do you recognize this? I've restarted NT, PC, and am trying to build out my workspace again from a new fully blank workspace, but I can't resolve it.

Pop up window error text:
"Unhandled exception: Stack Empty"


This is the exception in the trace file:

I'm finally noticing this now in the trace file and I assume this might be part of the problem, the resolutions don't actually match my monitor configuration...

2024-01-29 11:13:58:133 DisplayAdapters=2/Intel(R) UHD Graphics 630|NVIDIA GeForce GTX 1060
2024-01-29 11:13:58:133 Monitors=3/2100x3360|3584x2016|3840x2160

That only matches one of my monitors. Windows is showing my monitors as:

1 - 2560 x 1440
2 - 1200 x 1920
3 - 3840 x 2160

I tried a lot of things to fix this, but ultimately what seems to be causing this is the scaling setting in Windows display settings. If I set this to a number higher than 100%, the indicator window is opening off screen somewhere but I can't get to it (or at least NT thinks the indicator screen is opening, windows doesnt show it anywhere). Either way, when I keep this at 100% everything works as expected.








FWIW - The resolutions in the trace file are still incorrect, so I'm not sure what affect those have.
