Summary	0002467: sometimes get corrupted/compressed data graph after playing computer games
Description	This just started happening recently, perhaps after I installed a Samsung 950 Pro SSD (it is not my boot drive, just for gaming). After I exit from a game (tested with Fallout 4 and Divinity: Original Sin EE), then display the graph to review system temperatures. For a moment the graph displays normally, then switches to a "scrunched" view as shown in the accompanying image. Once graph is corrupted like this, it does not recover until program is closed and re-opened.
Steps To Reproduce	> start SpeedFan > on Charts page, enable all 9 sensors for graphing Display is initially normal, except that the HD2 (Samsung SSD) line usually does not draw all the way across the graph like the others do > start Fallout 4 and play for awhile > close the game, Restore SpeedFan, which is set to Charts page; graph will momentarily be normal, then will flash and show the corrupted display.

Gorlash 2016-01-10 04:29 reporter ~0007949	I figured out what caused this, and how to resolve it, though it is still a bug. I had installed a Samsung 950 Pro SSD, 512 GB on my machine. It is connected via a PCIe M.2 adapter card. I installed the Microsoft NVMe drivers for Windows 7 (which I am using). The card works wonderfully, and provides nearly RAM-level speeds!! However, it was shortly after I installed that drive, that SpeedFan 4.51 began exhibiting this issue. So I went to the graphing page, and I de-selected HD2 (the new SSD). This action appears to have solved the problem. Since I'm not especially worried about temperatures on this SSD, this solution is adequate for my purposes, and resolves this issue for me. However, wanted to let the maintainer know about it, as it might be useful in debugging the issue, and it may come up again, since this drive is so popular.
