Apparent Memory Spike Crashes Issue: After extended sessions of playing the Sunless Citadel, GM VTT would appear to have a VRAM spike that caused the screen to black out. Screen would return with UDL/FOW glitched and revealing everything on the GM VTT without UDL/FOW shading. Also, GM would then lose functionality of the VTT, as it would appear the mouse was clicking 3 or 4 inches away from the indicated cursor. GM had to close Chrome and reload/relaunch the game. The first occurance was after 3 or 4 hours of play on the Citadel Map. Second occurance was after a similar amount of time, 3 or 4 hours, this time 1 hour on Citadel Map, 3 hours on Grove Map. Both times, after resetting Chrome, the GM VTT would only be stable for 5 or 10 minutes before crashing after the initial crashes. I am new to Roll20, and have only been using UDL/FOW. It has been fine functionally, working as expected except for this bug, which in my experiences appears to be a VRAM spike causing crashes.

Edit: VRAM Performance was checked after a fresh full computer reboot. After 10 minutes idling it shows my GTX 650 (yes, I know, it's old) is clocking 90% load at idle, just sitting with the map open and one pop-up window exploded out onto a second monitor.
