Summary	09055: BGFX using backend vulkan crash MAME
Description	Hello. Thanks for reading my topic. If BGFX use backend vulkan happen an crash in MAME for some games. When the game is totally loaded in sequence MAME is halted for several seconds and crash not returning to main UI. That issue happen in games using the drivers below : arsystems artmagic coinmstr lethalj konamigx megaphx pntnpuzl upscope In moment is better use backend opengl. BGFX using opengl and vulkan has similar performance. Have an good week and new happy year.

No.22724 hap Developer 21 days ago	FWIW this still crashes for me, like I commented in the related MT report: mame gokuparo -video bgfx -bgfx_backend vulkan I haven't tried the other games you mention. As I said there, maybe bgfx vulkan disagrees with the screen size somehow.
No.22726 Augusto Tester 21 days ago	I want known MAME games thus I had loaded an high number of games and drivers and the only issues was bgfx crashing if using vulkan and strange slowdown in only 3 drivers ( seibuspi bizarre bug not using totally the cpu, bublbobl and cedar_magnet). BGFX support for vulkan was added in 2015 and I not remember if the games in the list had issues.
No.22737 Robbbert Moderator 21 days ago	I don't get any crashes, and I didn't test them all, but some of them produced a black screen instead of what should be there. megaphx, gokuparo, lethalj. So since there is an issue I'll confirm it (even though no crash dump has been provided).
No.22743 Augusto Tester 20 days ago edited on: 20 days ago	Thanks Robbbert for your reply. With you not happen crashes. Here all games in the list crashes. You use windows and nvidia GPU ? If yes only happen in Linux ? Tested only in Ubuntu 24.04 with nvidia driver 470. I not has information if happen with Radeon GPUs too.
No.22757 Robbbert Moderator 18 days ago	I'm using Windows 10 with a NVIDIA GeForce GT710. You need to provide a crash dump if you want any progress.
