I'm on Ubuntu 20.10, default desktop, nvidia-driver-460, Quadro M1200 GPU, and VLC also crashes for me whenever I try to take a snapshot.
However, I don't get the gl information logs mentioned by OP, is just says "segmentation fault". I tried reverting to 450, and it still segfaults. The `--verbose 2` messages corresponding to me clicking the take snapshot button in both cases are: ``` [00007f23600013b0] main vout display debug: VoutDisplayEvent 'mouse button' 2 t=6 [00007f23600013b0] main vout display debug: VoutDisplayEvent 'mouse button' 2 t=7 [00007f23600013b0] main vout display debug: auto hiding mouse cursor [000055c87ad2f7e0] pulse audio output debug: suspended [000055c87ad2f7e0] pulse audio output debug: changing sink 0: alsa_output.pci-0000_00_1f.3.analog-stereo (Built-in Audio Analogue Stereo) [00007f23a40c2d80] main encoder debug: looking for encoder module matching "any": 21 candidates [00007f23a40c2d80] main encoder debug: using encoder module "png" [00007f23a4708060] main filter debug: looking for video converter module matching "any": 23 candidates [00007f23a4708060] swscale filter debug: 1280x720 (1280x736) chroma: I420 -> 1280x720 (1280x720) chroma: RV24 with scaling using Bicubic (good quality) [00007f23a4708060] main filter debug: using video converter module "swscale" Segmentation fault (core dumped) ``` Also like OP mentioned, PrtSc does not work on full screen. Outside of full screen it works. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-460 in Ubuntu. https://bugs.launchpad.net/bugs/1913633 Title: nvidia-graphics-drivers-460 causes vlc to crash when taking video snapshot Status in nvidia-graphics-drivers-460 package in Ubuntu: Confirmed Bug description: vlc 3.0.11.1-2 would happily take video snapshots with version 450 (and earlier) of the drivers, but crashes instantly every time with 460. me@mine ~$ vlc VLC media player 3.0.11.1 Vetinari (revision 3.0.11.1-0-g52483f3ca2) [000055acea1745b0] main libvlc: Running vlc with the default interface.
