It might be helpful to get more information about your configuration:
diff --git a/src/screen.c b/src/screen.c
index b762f1e2..38cabdab 100644
--- a/src/screen.c
+++ b/src/screen.c
@@ -533,6 +533,10 @@ bool Screen_SetSDLVideoSize(int width, int height, int bitdepth, bool bForceChan
SDL_RenderPresent(sdlRenderer);
SDL_GetRendererInfo(sdlRenderer, &sRenderInfo);
+
+ fprintf(stderr, "SDL_VIDEODRIVER=%s\n", SDL_GetCurrentVideoDriver());
+ fprintf(stderr, "SDL_RENDER_DRIVER=%s\n", sRenderInfo.name);

bIsSoftwareRenderer = sRenderInfo.flags & SDL_RENDERER_SOFTWARE;
if (bitdepth == 16)
You can override the video/render driver using environment variables:
$ SDL_VIDEODRIVER=KMSDRM SDL_RENDER_DRIVER=software ./hatari
For SDL_VIDEODRIVER you can try: x11 | wayland | KMSDRM | RPI
For SDL_RENDER_DRIVER: opengl | opengles | opengles2 | software
