TUN issue in Windows 7 was resolved in new singbox core SagerNet/sing-box#3659

Necessity of recommendations

I tested the updated sing-box (sing-box-1.12.19-windows-386-legacy-windows-7) and so far my impression is that the original issue is resolved (the tunnel closing immediately) but now I get a new error which I've never seen before and the connection is very slow. The profile I used (after exporting with Tun mode enabled) works in Throne without issues for weeks including today; and no custom settings - just Throne 1.0.13 with only "System proxy" enabled and an imported subscription. So my profile and subscription are good.

The error I get repeatedly on most (or all) sites I tested it on:

←[31mERROR←[0m[0100] [←[38;5;29m465071885←[0m 14.99s] dns: exchange failed for www.googletagmanager.com. IN A: tls: failed to verify certificate: x509: certificate is valid for 8.8.8.8, 8.8.4.4, 2001:4860:4860::8888, 2001:4860:4860::8844, 2001:4860:4860::6464, 2001:4860:4860::64, not 8.8.8.8

In the logs I also see this popping out periodically (never seen this in Throne, including today) taking 5-9 seconds each:

←[36mINFO←[0m[0068] [←[38;5;183m3243223719←[0m 8.88s] outbound/vless[proxy]: out

From config.json:

I'll need to test it in Throne with sing-box updated to 1.12.19.

An update:
for me the original issue is resolved but the new error still renders the Tun mode unusable: the connection is either too slow (up to half a minute to open a page), or like it's with YouTube - the video playback doesn't start for any video. Connection is very slow and incosistent.
I did a lot of testing with different configs, settings and DNS and noted the results in the SagerNet thread mentioned here in the original post by Chara-Freedom.

I will continue with this after an update of either Throne or sing-box unless I missed something.

Wait for an update on throne, you may need to tweak some settings to get it to work, but i cannot guarantee anything as I don't have access to a windows 7 machine.
