Graphics artifacts when using Ubuntu

Question

I'm having this problem since I installed Ubuntu for a course that I'm doing.

I am getting graphics artifacts (see screenshot below) in many applications (some buttons on Zoom, but mostly on games like Minecraft, CSGO and Krunker.io).

If someone could help me I would be grateful.

My hardware:

It's an old computer with a i3 processor(Intel® Core™ i3-3220 CPU @ 3.30GHz × 4 ), a onboard graphic card(Intel® HD Graphics 2500 (IVB GT1)) and 4GB of RAM

Ubuntu 20.04.2 LTS | Kernel 5.8.0-59-generic

Thanks Freddy, but i have already try this solutions, and unfortunately nothing has changed — levi-manoel, Jul 17 '21 at 01:39
Read this ... if you can turn on something like "sync to vertical refresh" in your game, try that. — Murray Jensen, Jul 17 '21 at 04:23
Thanks Murray, but not the solution yet. i'm gonna to see if there is any driver to update, and about the sync, he only thing related is the vsync, and i have tested whit that disabled and enabled. And I have edited the post with more info on the hardware :) — levi-manoel, Jul 18 '21 at 02:04
Didn't work too :(. The worst thing is that I didn't find any image similar to my screen in any place — levi-manoel, Jul 20 '21 at 01:26
PS: edit your question and show Ubuntu version and kernel version... — Murray Jensen, Jul 20 '21 at 05:14
I'm gonna edit the post now, my kernel version is in the list :(. Is safe try to upgrade the kernel to 5.13? — levi-manoel, Jul 21 '21 at 00:39
Yes, try to upgrade to a newer kernel or downgrade, see askubuntu.com/questions/1331116. — Freddy, Jul 21 '21 at 02:25
I checked a couple of our Ubuntu 20.04.2 LTS machines and the kernel version was 5.4.0 in both cases (actually 5.4.0-77-generic) ... how did you get you get 5.8.0-59-generic on your machine? — Murray Jensen, Jul 21 '21 at 13:54
Firstly thanks you two by helping me, and i have just installed the ubuntu normaly, downloaded the iso, used Rufus to make a boot pendrive and installed this on mt machine — levi-manoel, Jul 22 '21 at 00:37
So, i have installed the version '5.13.0-051300-lowlatency' the triangles are gone finally. — levi-manoel, Jul 22 '21 at 01:20

Just for the record, according to this ...

OpenGL rendering missing some triangles, why and how to fix

... it's an issue with Intel integrated graphics (often HD 2500) and kernels between 5.8.0-49 and 5.12.5.

which may be fixed by

Installing a newer kernel or rolling back to an older one ...

This may help with rolling back to an older kernel, and this may help with installing a newer kernel.
