In particular, in DOTA 2, GTA 5, and FIFA 2018. However, our test of the UHD 620 integrated in the popular 8th Gen Intel Core i5-8250U quad-core processor showed some noticeable performance improvements in some games when compared to our previous test of the i5-7200U dual-core / HD 620. Both of these basic integrated graphics processors are suitable for some entry-level casual gaming and multimedia, including Ultra High-Definition videos. The new version has only 100 MHz higher clock speed as the main difference. Specs-wise, the Intel UHD 620 is nearly identical to the previous HD 620 of the 7th Gen Core U. If anyone has any ideas to diagnose this further or fix it, any help would be appreciated.The Intel UHD 620 Graphics is used in the widely adopted 8th Generation Intel Core U-series laptop processors.

I haven't found any other ideas searching these forums or elsewhere. versions, but at least it suggests it should be possible to fix. That doesn't tell me much though, since it'll have different kernel, kwin etc. To make sure it's not just a hardware issue, I tried a Kubuntu live CD, and that seems to work fine (using the modesetting driver).

I'm wondering if the Kwin compositor could be to blame, but it seems to still happen with the compositor disabled. I've tested with Youtube and see the same problem, so presumably it's not related to the player. This happens with VLC (regardless of what I selected for 'Hardware accelerated decoding'). I've enabled VA-API and VDPAU, and GuC/HuC (the problem was there without these, and persists with them). I've gone through the wiki article, and have found the least problematic setup is with the intel driver installed, with the TearFree option enabled.

Does anyone have any further suggestions to diagnose or solve the problem? There are brief screen freezes every few seconds, which are much worse with an external projector or monitor connected via HDMI. I'm seeing glitches with Intel HD 620 graphics (integrated graphics on an i7-8550), particularly with video playback.
