I'm having the same problem

iamSlightlyWind commented 3 years ago

Somehow this also just happened to me. Not sure how it was produced, but I can't reproduce nor revert. Pretty much all I did was delete the app's data and it happened. Reinstall or delete retroarch/delete data did not help.

Also having this issue. I can set my Video Driver to 90 degree rotation which fixes PPSSPP but messes my other cores.

sorry for necroposting, but you can modify this setting while the game is running and save it as an override specific for the content or emulator. in my case, PPSSPP core was misbehaving and all other cores were just fine, so I opened a PSP game, went to the main menu, modified the rotation to 90 degrees, went back to the quick menu, into overrides and saved the override as core-related. now whenever i load a game on PPSSPP, it also loads the changes on general settings, which includes the 90 degree screen rotation. if i load other cores, the setting is left as default.

My issue is exactly like Panderner's with the Landscape photo being as mine is on an Android tablet HPad 5. There is something definitely wrong in the coding for PPSSPP and its rendering of Vulkan. I am using F-droid's version, but have used the RA Plus and normal versions (the older version seems to work however, sound glitches too much and when I updated Core, went back to the screwup. ) The older core I believe was 1.18.#. However, I will attempt to try CharlesAnjos solution, but it is only a temporary fix as should something happen where I must delete the App, or change hardware, have to go through this all over again.

Okay, may have found a solution. Under normal Video Driver configuration, have it set to Vulkan with whatever other settings you would like to have. Under PPSSPP and a game you are running, under Core Options > Video, set the Driver to NONE. Close out content, close out RetroArch, jump back into PPSSPP and run your game. On mine, the video and game orientation was correct and even rotated normally when the tablet rotated. If anyone else does this could they confirm the fix? Thank you.

It really works, thank you! But if I turn on the volcano again, the next time I start retroarch the screen rotates again.

miklecake - make sure to SAVE your configuration on RetroArch and possibly in the Core settings as well. Thank you for the verification

it works but it's a lot slower, like it's using a software rendering.
