🪰 Viewer Bug Reports

I'm experiencing intermittent hangs and crashes in both Firestorm and the official Second Life Viewer on Windows 11. Firestorm has generally been more troublesome, but switching to the official Viewer has not eliminated the problem. The issues are not limited to busy regions, logging in, or teleporting. Even after adjusting the official Second Life Viewer's preferences conservatively, problems have also occurred at home and during ordinary activities, including unpacking and managing inventory, viewing images, changing outfits, and changing group tags. Busy shopping regions can also become extremely laggy. I've seen mixed results when changing group tags: some changes completed without a problem, while another caused the Viewer to freeze and crash. I also had one Windows Reliability Monitor incident report that SLPlugin.exe had stopped working, although I don't know whether it is related to the wider issue. The problems became worse around the September 2026 Windows update, but I cannot confirm that the update caused them. Lowering the Viewer's graphics settings and trying other troubleshooting steps have helped reduce the problems, but they have not eliminated them. I cannot reliably reproduce the crashes on demand. I've experienced Bugsplats, freezes, an avatar continuing to walk while the Viewer is unresponsive, gray screens, and most times I'm offered the chance to look at my IMs before crashing. System information Laptop: MSI Raider GE68 HX 14V CPU: Intel Core i9-14900HX RAM: 32 GB GPU: NVIDIA RTX 4070 Laptop GPU Operating system: Windows 11 I previously contacted Linden Lab Support about Viewer performance and provided diagnostic logs privately when requested. I was subsequently directed to use this feedback portal. I'm reporting this because the intermittent hangs and crashes affect everyday use across both Viewers, not just performance in busy regions. I don't know whether the incidents share a common cause. Related report: Crash Problem — reports crashes in both Viewers on busy regions.

Every time I log in, while its says Loading world, the music stream for whichever land I am in kicks on FULL VOLUME, even if I have the sounds muted in-world, if we use headphones it blasts full volume hurting our ears

The audio quality is poor with a Bluetooth headset, when the voice chat is active, even if I don't say anything, the viewer is activating the microphone all the time. It only gets better if I turn off the voice. My operating system is a Windows 11. This is also happening in the beta versions of Firestorm, but it doesn't occur in release 7.2.4

Got a notecard from Dench Designs, and opened one of the textures embedded therein. Instead of the old "Copy to Inventory", it says "Copy to Inventor". Looks like somebody accidentally chopped off the Y? (Very minor bug, but should be an easy fix.)

From my Windows Event Viewer the error is...

I've tried everything under the sun, clean installs, cache clears, usin' different versions of firestorm and second life viewer, clean install of my 4090 drivers, rolling back those drives, swapping out my modem through xfinity, used AI, and nothing works! It's to the point I can barely log in and do anything, please if there are any fixes or if this is a known issue bein' worked on let me know!

See https://jira.firestormviewer.org/browse/FIRE-36985 . Official sl, firestorm and other sl viewers have multiple instances in the dock and at activity monitor. It happen when i startup a viewer and i can quit them but they appear sometimes when i teleport again. It is only with sl viewers for me, not with other apps.

I present the same model (a small avatar accessory) with 2 different sets of LOD models. In each case the lowest LOD model has been 'zeroed out' to 18 tris as is typical in this use case. Triangle counts are as follows. * Model 1 - High 63040 (36k virts), Med 15760, Low 3940 * Model 2 - High 15760 (10k virts), Med 3940, Low 3940 Both of these models are visually indistinguishable in use. The DAE files prior to upload are sized as follows. * 63040 tris - 9.2mb * 15760 tris - 2.2mb * 3940 tris - 500kb Working on the dae sizes alone ... * Model 1 - 11.9mb * Model 2 - 4.9mb However .... * Model 1 - Download weight 0.7 * Model 2 - Download weight 3.1 When worn ARC is equally broken (as reported in firestorm) * Model 1 - ARC 319 * Model 2 - ARC 672 Objectively Model 2 is better for performance. Duplicating the mesh for 2 detail levels is punished to the point that using a sub division surface modifier to generate an insane 63k tris high model results in 'better consumer numbers' at intended object scale (it's also cheaper to upload). In addition to model duplication being unnecessarily punished, the scale component of Li accounting is fundamentally flawed and pushes creators into a situation where large items need to be low poly and tiny (often worn) items are best high poly! No wonder everyone's avatar is solid in wire-frame. This model is a small avatar accessory. Obviously the example mesh is over detailed, 'unoptimized' and created using techniques best suited to slow rendered content rather than real time. The point is why should anyone bother with 'low poly' when this gets the-job-done and is predictably rewarded.

Second Life keeps crashing on both the regular viewer and Firestorm viewer whenever I am on a busy sim. It will happen even when there's only about 10 other avatars around me/ I tried clearing my cache, lowering graphics, filimg an AMD report and turning off play media and it still is not helping. My laptop is only three years old so that's not the issue either.

There's a visual glitch when using more than one BOM texture layer on a Universal Aux channel if there's partial transparency in the texture using Blinn-Phong textures. I've made BOM textures with partial transparency for rigged fairy wings, so that customers could layer a stripey texture on top of the main wing texture. However, it's as if there's an outline of 100% transparency around the edges of the upper stripey texture that punches a hole straight through the underlying wing texture as well. It shows up the most when in front of a bright background. I tried making the stripe texture completely black with a 100% transparent background by converting it to a vector and then converting it back into a raster image in Photoshop, and this minimizes the issue so that it's only visible if you're very zoomed in, but this means there can't be layered BOM textures with blended edges at all on the Aux channels. I had envisioned being able to make add-ons like colorful peacock 'eye' spots, faded edges, etc so people could really customize their wings' look, but this doesn't seem to be possible right now.It happens whether the files are PNG or TGA, with or without an alpha channel.Since the main wing textures have partial transparency, changing the blend mode to alpha mask would not solve the issue. Hopefully you can see the problem in the screenshots. You might at first think it's the white outline 'halo' issue but no, it's actually that the edges have an outline that are completely clear so the background shows through.

Steps to Reproduce: STEP 1: Enable Front View. STEP 2: Switch the camera back to Default View. STEP 3: Trigger a teleport failure. Actual Result: Firestorm crashes without any error message. Expected Result: The viewer remains running and displays the teleport failure message. Impact: The user must restart the viewer. Additional Note: The issue appears to be reproducible when switching from Front View to Default View before a failed teleport. The problem has been observed on multiple systems with different hardware configurations, making a hardware-related cause unlikely. Environment Firestorm Release: 7.2.4 Build 80712 Operating System: Windows 11 64-bit Observed on multiple systems with different hardware configurations.
