[Remove lines written inside brackets [], but nothing else]
Game Name?
Mario Kart Wii (PAL)
Game ID?
RMCP01
What's the problem? Describe what went wrong in few words.
3D objects flickering on and off the screen, fairly constantly. Happens in menus (swirling cup in background) and in races. Only happens with PAL60 is disabled, works fine with PAL60 enabled.
What did you expect to happen instead?
The above phenomena to not happen, and for the models to appear on screen smoothly when PAL60 is disabled.
What steps will reproduce the problem?
[Don't assume we have ever played the game and know any level names. Be as
specific as possible.]
- Disable "Use PAL60 Mode (EuRGB60)" in Wii configuration tab
- Load Mario Kart Wii
- Go past the start screen, and past the "Choose Number of Players" menu
- Optionally, go into a race, the effect is worse
Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
4.0-5222
Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Yes. This doesn't happen in 4.0-4250 (2 months old), but it DOES happen on 4.0-4803 (1 month old) and the latest New-Zelda-HLE branch (4.0-4883-dirty).
What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
OS - Windows 8.1 Pro
CPU - Intel Pentium G3258 (overclocked to 4.2GHz)
GPU - Intel HD Graphics
Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
Sorry, no screenshots for this one. I tried to get a video dump but for some reason Windows decided to make the resulting file absolutely inaccessible to anyone and anything, including any administrative accounts :(

Wow, Google Code is worse than I thought. I can't edit the original issue message to get rid of the bracketed comments I forgot to remove...

Don't worry about it. I don't have Mario Kart Wii, so I can't confirm this issue or anything, but it sounds like something PAL60 could do.

I think you forgot to mention that it's only a Direc3d issue (OpenGL is fine)

Just tried it out on the latest master. Looks like it doesn't happen anymore.

It's happening currently to me with 5.0-RC using OpenGL (using Linux with nvidia).

Fine, sounds questionable to me.

It's happening on latest master for me. 4.0-7662
But only on DirectX11, OpenGL is fine.

I was a little surprised, but it shows up in a Fifolog.
When played back on OpenGL, no flicking. When played back on DX11, 3d objects flicker.

I bisected it to https://github.com/dolphin-emu/dolphin/pull/1392
4.0-4441 is not flickering and 4.0-4446 is flickering.
So maybe it's some annoying depth issue?
Updated by Armada over 8 years ago
While debugging the issue I've found that frames in which 3D models dissapear have twice as many draw calls as regular frames. In between those drawcalls it did draw the frame correctly, but didn't swap it out. Instead it clears the color buffer without clearing the depth buffer and continues drawing the next frame. So essentially it pulls down 60Hz to 50Hz by skipping a swap every few frames, a big waste of processing power.
The reason models dissapear is likely due to the fact that the previous depth buffer is still there, this can be a problem on backends where depth emulation isn't 100% accurate yet.

I've gotten confirmation that OpenGL works fine for this.

Yeah, was always DirectX11.

reread the issue. It should be fixed by 5.0-440 -> https://dolphin-emu.org/download/dev/40f4308dc2120ce4e105008f3cb46b6a1c553e64/
