Congrats to whoever on the recent upgrade of KDEPIM to KDE 5 on stable Gentoo. So far as I can tell, it seems to be working fine. Except ...
kmail's window is one of those random corrupt blocks of video memory that's totally (a) useless and (b) looks like nothing to do with kmail. Strangely, it's the only one of the korganizer programs that fails. All the others draw a perfectly happy window.
After some comparison with a working KDE5 system, the console log for kmail on the failing system looked like:
Code: | paul@acer ~ $ kmail
pp: Failed to translate a shader for depth1fs
pp: Failed to translate a shader for blend2fs
pp: Failed to translate a shader for color1fs
pp: Failed to translate a shader for blend2fs
Pass a valid window to KWallet::Wallet::openWallet().
org.kde.pim.webengineviewer: It's not necessary to check database now
this does not work on a KActionCollection containing actions! |
The "pp: Failure" lines are Bug 99549 - pp: Failed to translate a shade.
I changed my settings using driconf to remove Morphological anti-aliasing based on Jimenez' MLAA (me niether) to 0, and the problem went away.
IIUC the problem is specific to old radeon video cards. _________________ Greybeard |
