If you have Intel Graphics HD, Intel Graphics HD2500 and Intel Graphics HD4000, and are using the 64bit version of Firestorm 5.0.7 or later, on Windows 10, refer to this page.
This is a known issue with recent Intel graphics drivers, affecting other graphics applications besides SL viewers. Please refer to FIRE-21264 for information and known workarounds.
If you start experiencing graphics issues after a Win10 update, such as driver crashes, or simply very poor performance, the first thing to try is a full computer reboot.
If you have Intel HD 2000 or 3000 graphics, refer to this page.
If your laptop has an Intel CPU and also has either an AMD or Nvidia graphics system, it may have the ability to switch between the Integrated Intel graphics or power savings, or the AMD/Nvidia for performance. But sometimes Firestorm isn't automatically configured to use the high performance graphics.
You can confirm this issue by looking at Help → About Firestorm and checking the name of the graphics card listed. If it says Intel, please follow the steps on this page.
This mysterious flashing problem has been reported numerous times now and after some investigation we believe we finally have a repro for what's causing the issue. We do not yet know the specifics of exactly which systems are affected.
Typically the issue arises when Worn Rigged Mesh is in view and has at least one texture containing alpha and set to alpha blend mode. Alpha masking and emissive mask do not reproduce the problem.
We have also verified that this reproduces using the Official LL Viewer.
The Following Table shows which systems and drivers we have tested and whether they reproduce the Flashing Issue.

The Driver Version linked in the above table (DRIVER VERSION: 184.108.40.206.4352 & 220.127.116.11.4352) Has not reproduced the issue for us and is the Driver we recommend that you download direct from Intel.
If you receive the following Message when installing the Intel Driver:
The driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer manufacturer.
This is an indication that you have an OEM Driver installed by the manufacturer. This Leaves you with two options:
At Your Own Risk
If decide to wait for an update from your computer manufacturer, or are simply uncertain about removing an installed driver, the following steps may help to make things more tolerable for you until your drivers are updated.
