Hi Hamish, If it's oldish hardware then https://forum.sparkylinux.org/index.php?topic=4195.0 suggests it could be your choice of theme which is taxing the X server. I expect the hardware's resources can be overwhelmed by the requirements and normal hardware methods get switched to software. Or something.
launchpad.net used to have a very annoying bug where they put all their little icons into one very tall PNG, tens of thousands of pixels tall, which Firefox then tried to give to the Nvidia graphics driver. It ‘worked’, but caused a delay of many seconds, making the web site unusable. Both Firefox and Nvidia were required to trigger. -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2020-07-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
