After updating to media-libs/mesa-21.2.0_rc2 and rebooting (required) the x server screen does not display until refreshed by, e.g., a console swap. So the display is initially a black screen with the cursor, which does move with the mouse, but a swap to (e.g.) vt2 and back to vt7 displays the log in screen. After a log in (which has to be typed blind) I get a partial display update with only the top ~10% of the screen displayed. May be related to/duplicate of https://bugs.gentoo.org/show_bug.cgi?id=803050 Weird things about my system: I'm using a 4k display in PORTRAIT mode. I'm using the integrated Intel 630 hardware (Asus Prime Z370-A motherboard.) I saw a missing driver when starting an app which uses the camera after the rebuild, before the reboot, but no other problem. Reproducible: Always Steps to Reproduce: 1. merge media-libs/mesa-21.2.0_rc2 2. reboot 3. Actual Results: Black screen on vt7 (x server) Expected Results: Login screen displayed immediately Linux hippopopus.jbowler.com 5.13.4-gentoo+systemd #1 SMP Wed Jul 21 09:09:53 PDT 2021 x86_64 Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz GenuineIntel GNU/Linux The problem happens with 5.13.3 as well.
Created attachment 726562 [details] emerge --info media-libs/mesa
The package settings in the emerge --info attachment refer to the previous package (I had to mask 21.2.0_rc2 to be able to report this bug!)
Probably i have the same problem when running monero-wallet-gui: the screen goes black and only the mouse cursor is updated until i restart X. Downgrading mesa resolved the problem for me. Intel Corporation UHD Graphics 620 here.

Why? It seems to be a display update issue; I was able to get a completely or partially correct display by flipping to a console then back (Alt-Shift-F2, Alt-Shift-F7). So the rendering seems to be occurring but not the display update. Since my display is portrait it might have been some bug in the handling of the rotation, but it happens on your system too so it isn't that. I assume it does work on quite a lot of systems. The common factor seems to be the use of the intel driver.
I confirmed this bug is not fixed in: =media-libs/mesa-21.2.0 Fix (apart from not using Gentoo desktop) is to mask: >=media-libs/mesa-21.2.0_rc2
Can confirm John Bowler's report. On multiple machines with UHD Graphics 630 rendering is too slow to be usable with vanilla 5.13.9 and mesa-21.2.0. Older Chipsets (like Haswell) working OK. Had to downgrade to mesa-21.2.5
OK, sorry, see me row back. Adding "iris" to VIDEO_CARDS as stated in Bug 803839 solves this issue.
Adding "iris" to the VIDEO_CARDS variable in make.conf also makes the total-non-redraw problem go away. That's not really surprising since it is apparently using a completely different driver. The whole mess of settings is documented here: https://wiki.gentoo.org/wiki/Intel#X_drivers So my system is a gen 8 (apparently; gen 8 seems to be Core i7) and I had "intel i965" but now I apparently need "intel i965 iris". There's something on that web page about it now being used in xorg-drivers: > Important > Beginning with x11-base/xorg-drivers-1.19, the x11-base/xorg-drivers package (in addition to the mesa package) includes support for the i965 USE flag. This will omit selection of the deprecating x11-drivers/xf86-video-intel driver in favor of the more maintained, generic modesetting DDX driver built into x11-base/xorg-server. I don't know if there is some hidden problem there if Intel are blacklisting i965 on G8/I7, but I don't see any issues. It does imply that removing "i965" from the list might cause issues, but I haven't tried that. It does seem that this would best be fixed inside the gentoo package configuration by, maybe, failing to ebuild mesa if a broken driver (the fallback, apparently) is going to be used. I'm pretty sure the instructions have changed since I first set up make.conf for my system; I don't think it was my error that left "iris" off the list. Since lspci can detect the broken config in user mode maybe the install step could fail. (I'm BSing here, but when this gets dropped into stable I imagine there will be quite a few annoyed people.)
I don't want to hijack anything here, but I have an i7-8665U (UHD 620) with VIDEO_CARDS="intel i965" and mpv video playback completely broke on my system when upgrading to mesa-21.2.1. After seeing this thread and changing to VIDEO_CARDS="intel i965 iris" everything started working again.
I faced a similar (same?) issue trying to go for mesa-21.2.2, coming from mesa-21.1.7: Having Gnome on Wayland, screen updates were lagging behind for seconds, typing was nearly impossible, with heavy CPU loads. Although only having UHD Graphics 620 (not 630), adding +video_cards_iris fixed the issue for me, too. I am running smoothly with mesa-21.2.2 now.
I've consolidated the different Intel-related VIDEO_CARDS options into VIDEO_CARDS=intel in mesa-9999.
