I’m happy to report that bug 5649065 (exploding meshes in native OpenGL Linux programs) which appeared in v580 (back in August 2025 !) has apparently been fixed in (or is not affecting, depending on how NVIDIA manages driver branches) v610.43.02.
I tried for the past two days to trigger it, on two different computers/GPUs (RTX 3070 and RTX 5070 Ti) during hour(s) long sessions in Second Life, and so far, so good !
Let’s hope that this bug will not get reintroduced in future versions…
One thing I yet don’t like with v610 is the fact that VDPAU is not working properly any more when two screens are connected (I suppose it’s because Xinerama support under X11 got dropped in v610): I had to switch VLC video output to Xvideo/XCB to be able to still use it when two screens are connected to the card…
