What's the problem? Describe what went wrong.

Dolphin displays textures with non-multiple-of-four heights differently from real consoles.

What steps will reproduce the problem?

See attached fifo log. This is from a modified version of the game, but probably it happens with any game that uses such textures.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes, 5.0-13614

Is the issue present in the latest stable version?

Yes

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

N/A

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

In Dolphin, the title screen texture (size 512x191) appears normally. On a real console, it's corrupted ("Starfox Starfox").

What are your PC specifications? (CPU, GPU, Operating System, more)

Reproduced on:
- ThinkPad T540p, Artix x64, 16GB RAM, integrated GPU
- AMD FX8320, Arch AMD64, 32GB RAM, Radeon RX590

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

Included patch file for the modified game if more testing is needed.

Actually it seems to be necessary that the height be a power of two, not just a multiple of four.
