[help][solved] Getting input lag on Bazzite (lemmy.nz)

Hi all, I have recently installed Bazzite, after previously being on Nobara.

I have been playing Dave the Diver and DOOM (2016), both through Steam, and I get pretty serious input lag. A second or more delay at times, generally when FPS is struggling.

I'm running on a laptop with integrated graphics, so the struggling integrated GPU is not a surprise, but I didn't have this input lag issue with the same games on Nobara.

Any tips on a setting or something to help this?

I have lowered graphics settings to help with FPS, but ultimately I am not going to be able to avoid occasional FPS dips. The mouse input is instant, it's just an issue with the keyboard.

Any help appreciated!

Edit with solution: it seems the problem is IBus, see this comment: https://lemmy.nz/post/23401044/15684126

Basically the solution is to add IBUS_ENABLE_SYNC_MODE=2 to /etc/environment and restart.

That’s getting old school. I had to do the same thing to get Shovel Knight to accept input properly about 10 years ago.

I sent a message to the dev about it, but there wasn’t a Linux port yet so they were stumped. I changed the repeat rate of the key input in kde and there it went like magic.

Another comment has this down to a bug in IBus, which is for supporting typing non-latin characters.

So I get a proper solution, mostly (I think a proper proper solution would be having the bug fixed)
