This very likely bisects to commit 688d6958682f96aaeb88aa8cc23cc5c9886a6be4 so I'm taking this bug. BTW how did you install plasma 5.11.3? Kubuntu artful has 5.10.5 by default.

Kubuntu artful has 5.10.5 by default. sudo add-apt-repository ppa:kubuntu-ppa/backports There is a specific repo for kde updates. > Or maybe not since this was seen also with nouveau. I will anyway try to bisect when this started. As of today, after another set of mesa updates, I do not see the issue on nouveau. I've reproduced this and trying to understand what's going on. This is caused by my patch that exposes sRGB visuals. Hello, could you please retry with using "sna" as the acceleration method? I will attach here required configuration file for testing this. You will need to copy this file to /usr/share/X11/xorg.conf.d/. Created attachment 135480 [details]
enable sna
(also please try again with latest mesa) Tried right now. Incidentally, I have always been working with SNA, since it is fine on haswell and snappier than glamor. I still see the issue with mesa as of 17.4 git snapshot taken on 17/11/15 07:30 commit id 65123e... I'll try again when a newer build of a mesa snapshot is available for kubuntu 17.10 (likely tomorrow). (In reply to sergio.callegari from comment #9) > Tried right now.

OK thanks, I was able to reproduce this just yesterday but today after update from oibaf not anymore .. so I'm really confused what this is about :/ My testing has been with older plasma 5.10.5 though as this is what the other bug 103655 is filed against. I will go through all the components today as I did replace dri and libGL of my own but later replaced by doing "apt-get install --reinstall" and menus still worked.

test case
Could you please compile and run this test application and attach what is prints? Does it create a visible window? Also please attach your glxinfo output. Many thanks!
Created attachment 135537 [details] [review] workaround This patch (that simply rearranges visuals) fixes the issue. As of today, with mesa 17.4 + git snapshot taken on 17.11.20 07:30 at commit 59ca0, I still see the issue. I do not know if the latest patch is in.
Please provide cmdline to compile the test application to save me identifying which libs need to be linked in.

output of glxapp (test application)
Tried the test application. See the attached file (hope I did it properly, this time) for its output. The application is not successful in displaying a window, but makes the window manager think that a window has been opened. In fact, the task manger starts showing a button for an unnamed window. Clicking the button does not rise any window, though and merely takes focus away from the previously focused window.

Yep, I believe I managed to isolate there what is happening with those Firefox menus, they get created with 32bit visual and are then invisible for some reason. Thanks for the output, will keep digging what causes this. Created attachment 135745 [details] [review] fix/workaround I've sent this patch to xorg-devel for review/discussion. Problem is that GLX may pick sRGB capable config for 32bit visual that is used for translucent windows and compositor (kwin) does not seem to do blending properly in this case as it seems not aware of sRGB at all. Another bug indicated that gnome-shell may have the same issue so I'm proposing to disable sRGB globally 32bit visual for now. Created attachment 135782 [details]
modified test case
The window decoration is a separate texture in kwin, so the decoration should be rendered normally even if the fbconfig is causing a blending issue with the window contents. I think it is more likely that binding the pixmap to a texture failed, and kwin is skipping the window entirely as a result.
I'm attaching a modified version of the test case that prints all the attributes kwin looks at, and also does the additional filtering and sorting of fbconfigs that kwin does. This version also sets GLX_ALPHA_SIZE to 8 and GLX_BUFFER_SIZE to 32.
Hi there my system has - Mesa 17.2.4; - KDE Plasma 5.10 on Fedora 26 and I think I am experiencing this problem.

One is the rendering results of krunner, panel and launcher menu, that is way too dark and then there are these invisible windows. Both get fixed by not setting sRGB capable config for 32bit visual, which I think is correct thing todo since there is only 1 such (non-conformant) visual exposed.

Yes, I believe the dark windows is a result of Qt not using the ARGB visual for those windows, so the background which is supposed to be translucent is solid black. I don't disagree with the solution, but I don't think these are blending issues; it's rather that applications are looking for a non-sRGB capable fbconfig associated with the ARGB visual, and either giving up or falling back to a non-ARGB visual after not finding one.

Yep having done some more investigation I do agree it's not about blending, it's about getting wrong kind of visual. I'll wait for review comments on the xorg change. Another problem caused by the new Mesa srgb visuals -- and assigning srgb to the special 32 bit composite overlay -- seems to be that the xf86-video-intel ddx will only give you a black screen under KDE Plasma 5, as tested with KUbuntu 16.04.3 LTS + distribution provided X-Server 1.19.3. Found this when i disabled depth 30 after testing my 10 bpc Mesa patches on top of the new srgb patch and stared at a black screen after logging in again. Works fine with the intel-ddx at X-Screen "DefaultDepth 30", or with the modesetting ddx at regular depth 24.

Yep, the symptoms are little bit different depending on gpu (different visual list) and how driver implements texture from pixmap with srgb (AFAIK not defined by any spec) :/ Hopefully the patch would be reviewed soon.

This bug causes issues on 'window level' and not for only some contents of window. I haven't been able to reproduce this after following commit landed to Xorg and I haven't received any new bugs on this subject. Resolving as fixed, please reopen if this still occurs. --- 8< --- commit c2954b16c8730c7ed8441fd8dba25900f3aed265 Author: Tapani Pälli <tapani.palli@intel.com> Date: Tue Nov 28 09:23:29 2017 +0200 glx: do not pick sRGB config for 32-bit RGBA visual This fixes blending issues seen with kwin and gnome-shell when 32bit visual has sRGB capability set.
