Package: libsdl2-2.0-0 Version: 2.0.14+dfsg2-3 Severity: normal Hi, SDL2 currently segfaults on imx8 hardware with the DRM backend when trying to use osk-sdl (currenty in NEW) when trying to use a cursor plane (so other applications should hit this as well):
[Current thread is 1 (Thread 0xffffa4ab4600 (LWP 2285))] (gdb) bt #0 KMSDRM_ShowCursor (cursor=<optimized out>) at ./src/video/kmsdrm/SDL_kmsdrmmouse.c:317 #1 0x0000ffffa64d028c in KMSDRM_CreateWindow (_this=0xaaaab75463f0, window=0xaaaab755f490) at ./src/video/kmsdrm/SDL_kmsdrmvideo.c:1839 #2 0x0000ffffa64add14 in SDL_CreateWindow_REAL (title=0xaaaaaf22eb20 "OSK SDL", x=<optimized out>, y=<optimized out>, w=<optimized out>, h=<optimized out>, flags=1) at ./src/video/SDL_video.c:1594 #3 0x0000aaaaaf223890 in main () This is due to fb = KMSDRM_FBFromBO(video_device, dispdata->cursor_bo); failing. The buster version works and above changes were reverted in current hg so 2.0.15 is working as well but a backport is non trivial since most of the code there got rolled back so backporting that would be rather invasive. Any suggestion how to best resolve that for bullseye (if at all)?
