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

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
