Mozilla Firefox is slow even if hardware acceleration is enabled?

Try enabling gfx.x11-egl.force-enabled in about:config to force the use of EGL1 and then restart the web browser.
If this works, enabling layers.acceleration.force-enabled can boost your performance even more by enabling OpenGL alongside EGL. 2
This also works on Flatpak if the security permissions are correct (use Flatseal3 if needed).

EGL - Native Platform Interface

EGL™ is an interface between Khronos rendering APIs such as OpenGL ES or OpenVG and the underlying native platform window system. It handles graphics context management, surface/buffer binding, and rendering synchronization and enables...

I'm still on the journey to using #Wayland rather than #X11 but there are a few issues which I'm not sure how to resolve.

Here's the scenario that I'm currently looking at. I have a separate #touchscreen which I can attach to my #laptop via an #HDMI connection. I can configure it to extend the usual monitor, say to the right. However, when I touch the touchscreen, it registers movement on the laptop's monitor even though I'm touching a location which should be to the right of it. With an X window set up, I can remap things using #xinput so that the touch is registered correctly but I haven't figured out a way of doing the same in Wayland. Does anybody have any ideas?

I've been looking at improving the usefulness of my separate #touchscreen when using a #program like #xournalpp for making sketches and writing on a display for other to see. It works OK with #X11 but the response to touches of the #stylus on the screen is a bit frustrating. However, with #Wayland, it seems to be so much better, which means the #hardware is fine and it's the #software that is not very sensitive.

The only issue I have now is that I can only get it work as a clone of the laptop display and not as a separate screen. This works with X11 though I have to adjust things a bit with #xinput. But in Wayland, touches on the screen as configured "to the right" of the main display map back to the #mouse #cursor on the main screen and not on the touchscreen itself. Does anyone have any ideas about a possible solution?

Today I had to give two different presentations in two entirely different places, neither of which had an #HDMI connection, which is the only #video output I have on my #laptop. Both still had #VGA, which is pretty ancient these days. Luckily, a few years ago, I bought an HMDI-to-VGA #adaptor but initially I had difficulty with using it, perhaps because of lack of full support in #KDE. Colours were sometimes different or flashed or gave some odd artefacts on the projected image. Happily, now things have been sorted out and everything worked really well. I was also using an extra #touchscreen and an #HDMI duplicator to send the signal to two outputs at once. Thanks to all the #FreeSoftware hackers who made this possible.
