[BUG]: pop'n music 9 (SLPM-65508) Changing the renderer while playing a song causes the song title to glitch

[SeruranBlue]

Describe the Bug

Changing the renderer while playing a song causes the song title (green text at the top of the screen) to glitch.
It happens with the default settings.
Once it glitches, it never returns to normal, after switching the renderer back or even loading a savestate.

Logs & Dumps

POP9_GS.zip
It seems that if you enter the song gameplay screen with the HW renderer, it is already broken although proper song title is displayed. because, if you take a GSdump without changing the renderer, the dump looks already glitched. (Entering with the SW renderer, it displays proper text in only SW renderer.)

Possibly better GS Dump (Taken after booting SW mode to preserve text)

I bet if you start the song in software mode (from the main menu), it'll never glitch

If my gamble is correct, the game will need the "Read Targets when Closing" HW fix. Or don't mess with the renderer while playing the game :)

Unfortunately the hw fix or starts game with SW renderer doesn't work for me if I switch the renderer.
(Well, the game plays flawlessly as long as I don't switch renderers, so I guess that's good enough for now.)

[refractionpcsx2]

well it kinda half works.

It comes back if you go back in to software again.

The read targets also does work, but switching back to hardware fails to load the texture (same as going from SW), so that's the separate issue here which needs fixing, the rest can be done with GS fixes
