Disable HW acceleration for Telegram or other QT apps

I need to use my GPU for rendering and apps like Telegram become slow as hell when i do so

Is there a way to make Telegram and QT apps rely on cpu only instead of GPU?

Re: Disable HW acceleration for Telegram or other QT apps

You could try and run them with LIBGL_ALWAYS_SOFTWARE=1 but whether that will be relevantly faster is unlikely. Afaik there are also some Qt specific environment variables but I'd have to try and dig that up

https://doc.qt.io/qt-5/qtquick-visualca … pplication might be also something to try.
