Should add an option for UI scale override #14527

Open hrydgard opened 3 years ago

hrydgard commented 3 years ago

Got a report on Discord by ゆかとし that on some TVs, PPSSPP's UI is way too small.

We previously had an issue about PPSSPP being way too large scaled on some tiny device, which would be the opposite problem with a similar solution.

We could override the default scale using the system name, and/or provide an option.

It could also be that we're just doing it wrong on Qt (the user reported they're using Qt.) Not that a Qt bug precludes adding a setting for UI scale or text scale.

Oh, yeah, absolutely. Didn't look very closely at the screenshot, or notice that they mentioned Qt, heh.

I'm experiencing the same problem using a 4K TV, even with display output set to 1920x1080 or 1280x720. The font just gets harder to read as there's less pixels to display the tiny letters.

The talk of Qt above prompted me to look into the screen scaling options for the GUI toolkit. I'm glad to say I found a workaround.

Launching with these environment variables set makes PPSSPP much more legible for me:

QT_AUTO_SCREEN_SCALE_FACTOR=0 QT_SCALE_FACTOR=0.25 ppsspp
