[sl-service-account]

Test plan:

1. Verify the viewer starts and can log in on a Windows system with any of the following video cards. Intel(R) HD Graphics (this one may be unsupported on 64bit Windows) Intel(R) HD Graphics Family (this one may be unsupported on 64bit Windows) Intel(R) HD Graphics 4000 Intel(R) HD Graphics 4400 Intel(R) HD Graphics 4600 Intel(R) HD Graphics 5500 Intel(R) HD Graphics 6000
2. Please note which video card was tested.

Expected: Log in without crash

This crash has increased significantly in 7.1.9.10515727195. My system with an Intel HD Graphics 4400 crashes on startup: https://app.bugsplat.com/v2/crash?database=SecondLife_Viewer_2018&id=1513508

This fix has been verified on Intel(R) HD Graphics 4400 & 4600

[igorlproductengine]

Passed QA. Verified on the Second Life Release 7.1.10.10622905308 (64bit) on Win10 in the scope of secondlife/iqa#323.

The viewer does not start in Win10 on Intel HD and Intel HD 3000 video cards - giving a message about problems with the driver. There is no crash.

The same behavior is on the current release 7.1.9.10515727195 viewer.

The viewer runs without crashing on the Intel HD Graphics 610 video card.

Taking into account the tested Intel HD Graphics 4400 and 4600 video cards, I consider the bug fixed.

Tested on: Win10: Intel HD and Intel HD 3000 screenshot:

Log_Intel_HD_3000: SecondLife_Intel_HD_3000.log Log_Intel_HD: SecondLife_Intel_HD.log

Win11: Intel HD 610 screenshot:

log_Intel_HD_610: SecondLife_Intel_HD_610.log

Failed QA. Verified on the Second Life Release 7.1.10.10622905308 (64bit) on Win10/OSX in the scope of https://github.com/secondlife/iqa/issues/323.

The viewer does not start in Win10 on the Intel HD 4000 video card - without giving a message about problems with the driver. There is the crash: https://app.bugsplat.com/v2/crash?database=SecondLife_Viewer_2018&id=1521049.

Failed QA. Verified on the Second Life Release 7.1.10.10708851543 (64bit) on Win10 in the scope of secondlife/iqa#326.

The viewer does not start in Win10 on the Intel HD 4000 video card - without giving a message about problems with the driver. I didn't completely check this issue according to the test plan because of the crash. There is the crash: https://app.bugsplat.com/v2/crash?database=SecondLife_Viewer_2018&id=1523757

yes the failure to link cannot be fixed yet. this patch turns this into a non-fatal error since the particular shaders that are failing are only for new features behind a feature flag.

looking at the latest call stacks from last night's testing it appears that they are different. those call stacks look more like #2434
