Mouse.cx/cy wrong in fullscreen mode

[mgedmin]

I'm following along the TCOD tutorial, and I noticed that mouse event coordinates are wrong in fullscreen mode.

In non-fullsceen mode, mouse.cx, mouse.cy range from (0, 0) to (79, 49), as expected, but as soon as I call tcod.console_set_fullscreen(True), mouse.cx, mouse.cy get values between (-56, -29) to (135, 78).

I'm on Ubuntu 19.04. I've pip installed tcod and got version 11.3.0. My screen is 1920x1080.

EDIT: I'm using a Wayland session, in case that matters.

The old renderers try to switch to exclusive fullscreen mode which often causes all kinds of problems. Any chance you can post a screenshot of your monitor when in fullscreen mode?

Also check if the SDL2 renderer has these issues (add renderer=tcod.RENDERER_SDL2 to tcod.console_init_root.) That should have more consistent results across platforms.

Here's a screenshot of the fullscreen mode:

Adding renderer=tcod.RENDERER_SDL2 fixes the problem.

Is that a screenshot of tcod.RENDERER_SDL or tcod.RENDERER_SDL2?

[mgedmin]

The screenshot was made without specifying a renderer, so whatever was the default?

Is there a way to check at runtime?

[mgedmin]

tcod.sys_get_renderer() returns 2 on my system if I don't set the renderer explicitly.

(Setting the renderer to SDL2 makes it return 3.)

Thanks. The default renderer is currently SDL.

It will probably be a while before this is fixed, and the fix will likely be just changing the default renderer to SDL2.

The old renderers have been removed, so this is no longer an issue.
