== Problems ==

Since {{revision|3.5-471}}, when using the MS Bluetooth Stack (the default bluetooth stack on Windows) Prime 3 will think that the wiimote is constantly disconnecting. Pressing a button on the Wii Remote will restore it, but it will disconnect again seconds later. Windows users can disable "Enable Speaker Data" to solve this problem, or move to either the Toshiba Stack or the DolphinBar.

=== Shader Compilation Stuttering ===

 

=== Bloom Offset ===

Prime 3 has noticeable bloom offset problems. It will have several copies of the bloom spread out from the source, and can be very distracting. The only solution is to disable "Scaled EFB Copy", but this has some issues of its own. See {{issue|5573}}.

=== Visors ===

The Scan visor will only work if '''Store EFB Copies to Texture Only''' is disabled. Though '''Store EFB Copies to Texture Only''' is forced off by the GameINI, visor issues may still occur if the graphics configuration window is opened during gameplay. Disable '''Store EFB Copies to Texture Only''' in the Dolphin GUI to avoid any problems.

=== Dot ===

When playing above 1x Native internal resolution, there is a dot in the center of the screen. It's small and easy to ignore, but it's always there. There is no fix for this problem.

 

=== The Black Bar ===

During Shader Compilation, stuttering can become so severe that it desyncs the GPU and CPU threads in Dual Core mode. The game freaks out over this desync, creating a black bar at the bottom of the screen, which takes up 15% of the screen space and "squishes" the game in the remaining space. The black bar will remain there from then on whether stuttering continues or ceases.

 

After {{revision|4.0-7517}}, enabling Virtual XFB or Real XFB will fix and/or prevent the problem. If XFB is disabled the problem may still occur. Details can be found in the [https://dolphin-emu.org/blog/2015/10/01/dolphin-progress-report-september-2015/#40-7517-derive-field-timings-from-video-interface-registers-by-booto September Progress Report].

=== {{s}}Savestates{{/s}} ===

=== {{s}}Pixelation Glitches{{/s}} ===

A large pixelated block may appear in the upper left area of the frame. It may only appear during movement (newer revisions) or be stuck there permanently (older revisions). To avoid this problem, use the D3D graphics backend. Fixed by {{revision|4.0-5523}}, and detailed in the [https://dolphin-emu.org/blog/2015/03/01/dolphin-progress-report-february-2015/#40-5523-fix-hashing-for-the-last-byte-by-mimimi February Progress Report]

{{image|MP3-Pixelboxes-cropzoom.jpg|Example of the pixelation, top half is blurred|br}}

=== {{s}}Refraction Slowdown{{/s}} ===

Refraction effects, such as raindrops on Samus' visor and the heat effect after firing her weapon for an extended period, cause slowdown on all backends. OpenGL is affected worse, though D3D is affected as well. It also has slowdowns when several grapple points (yellow pulsing) are present on screen at once. Even the strongest computers are affected by this issue, and there is no solution at this time. Fixed by {{revision|4.0-5124}}.

 

=== {{s}}Blue Startup Video{{/s}} ===

Since {{revision|4.0-216}}, the opening video is... blue. It goes away as soon as a wiimote appears on the screen or after a period of time. It has no effect on gameplay. See {{issue|6783}}. Fixed by {{revision|4.0-3334}}.
