Hi, when the SLI on my Nvidia GeForce GTX 970M is enabled, Thunderbird crashes immediately upon start. I also tried a few previous Thunderbird versions: same behaviour. When SLI is disabled, Thunderbird works correctly.

System: Windows 8.1, 64 bit Thunderbird version: 78.7.1 (64-bit) with hardware acceleration enabled Nvidia driver: 445.87

The following are the latest Crash IDs: bp-a76d524c-6f10-4a1c-8414-157350210208 bp-2b6cdacf-0979-49b6-a594-613850210208 bp-d10ae16a-8b90-4ecf-8304-ebdd80210208

Thanks for your attention

If it doesn't crash when HWA is disabled, then that's the best we can do at the moment.

Dear Wayne, thank you very much for the quick reply. I confirm that Thunderbird does not crash when HWA is disabled with SLI enabled. So, disabling HWA on Thunderbird solves the problem Again, thanks Corrado
